+Network priority cgroup
+-------------------------
+
+The Network priority cgroup provides an interface to allow an administrator to
+dynamically set the priority of network traffic generated by various
+applications
+
+Nominally, an application would set the priority of its traffic via the
+SO_PRIORITY socket option. This however, is not always possible because:
+
+1) The application may not have been coded to set this value
+2) The priority of application traffic is often a site-specific administrative
+ decision rather than an application defined one.
+
+This cgroup allows an administrator to assign a process to a group which defines
+the priority of egress traffic on a given interface. Network priority groups can
+be created by first mounting the cgroup filesystem.
+
+# mount -t cgroup -onet_prio none /sys/fs/cgroup/net_prio
+
+With the above step, the initial group acting as the parent accounting group
+becomes visible at '/sys/fs/cgroup/net_prio'. This group includes all tasks in
+the system. '/sys/fs/cgroup/net_prio/tasks' lists the tasks in this cgroup.
+
+Each net_prio cgroup contains two files that are subsystem specific
+
+net_prio.prioidx
+This file is read-only, and is simply informative. It contains a unique integer
+value that the kernel uses as an internal representation of this cgroup.
+
+net_prio.ifpriomap
+This file contains a map of the priorities assigned to traffic originating from
+processes in this group and egressing the system on various interfaces. It
+contains a list of tuples in the form <ifname priority>. Contents of this file
+can be modified by echoing a string into the file using the same tuple format.
+for example:
+
+echo "eth0 5" > /sys/fs/cgroups/net_prio/iscsi/net_prio.ifpriomap
+
+This command would force any traffic originating from processes belonging to the
+iscsi net_prio cgroup and egressing on interface eth0 to have the priority of
+said traffic set to the value 5. The parent accounting group also has a
+writeable 'net_prio.ifpriomap' file that can be used to set a system default
+priority.
+
+Priorities are set immediately prior to queueing a frame to the device
+queueing discipline (qdisc) so priorities will be assigned prior to the hardware
+queue selection being made.
+
+One usage for the net_prio cgroup is with mqprio qdisc allowing application
+traffic to be steered to hardware/driver based traffic classes. These mappings
+can then be managed by administrators or other networking protocols such as
+DCBX.

+6LoWPAN Linux implementation
+============================
+
+The IEEE 802.15.4 standard specifies an MTU of 128 bytes, yielding about 80
+octets of actual MAC payload once security is turned on, on a wireless link
+with a link throughput of 250 kbps or less. The 6LoWPAN adaptation format
+[RFC4944] was specified to carry IPv6 datagrams over such constrained links,
+taking into account limited bandwidth, memory, or energy resources that are
+expected in applications such as wireless Sensor Networks. [RFC4944] defines
+a Mesh Addressing header to support sub-IP forwarding, a Fragmentation header
+to support the IPv6 minimum MTU requirement [RFC2460], and stateless header
+compression for IPv6 datagrams (LOWPAN_HC1 and LOWPAN_HC2) to reduce the
+relatively large IPv6 and UDP headers down to (in the best case) several bytes.
+
+In Semptember 2011 the standard update was published - [RFC6282].
+It deprecates HC1 and HC2 compression and defines IPHC encoding format which is
+used in this Linux implementation.
+
+All the code related to 6lowpan you may find in files: net/ieee802154/6lowpan.*
+
+To setup 6lowpan interface you need (busybox release > 1.17.0):
+1. Add IEEE802.15.4 interface and initialize PANid;
+2. Add 6lowpan interface by command like:
+ # ip link add link wpan0 name lowpan0 type lowpan
+3. Set MAC (if needs):
+ # ip link set lowpan0 address de:ad:be:ef:ca:fe:ba:be
+4. Bring up 'lowpan0' interface

+Open vSwitch datapath developer documentation
+=============================================
+
+The Open vSwitch kernel module allows flexible userspace control over
+flow-level packet processing on selected network devices. It can be
+used to implement a plain Ethernet switch, network device bonding,
+VLAN processing, network access control, flow-based network control,
+and so on.
+
+The kernel module implements multiple "datapaths" (analogous to
+bridges), each of which can have multiple "vports" (analogous to ports
+within a bridge). Each datapath also has associated with it a "flow
+table" that userspace populates with "flows" that map from keys based
+on packet headers and metadata to sets of actions. The most common
+action forwards the packet to another vport; other actions are also
+implemented.
+
+When a packet arrives on a vport, the kernel module processes it by
+extracting its flow key and looking it up in the flow table. If there
+is a matching flow, it executes the associated actions. If there is
+no match, it queues the packet to userspace for processing (as part of
+its processing, userspace will likely set up a flow to handle further
+packets of the same type entirely in-kernel).
+
+
+Flow key compatibility
+----------------------
+
+Network protocols evolve over time. New protocols become important
+and existing protocols lose their prominence. For the Open vSwitch
+kernel module to remain relevant, it must be possible for newer
+versions to parse additional protocols as part of the flow key. It
+might even be desirable, someday, to drop support for parsing
+protocols that have become obsolete. Therefore, the Netlink interface
+to Open vSwitch is designed to allow carefully written userspace
+applications to work with any version of the flow key, past or future.
+
+To support this forward and backward compatibility, whenever the
+kernel module passes a packet to userspace, it also passes along the
+flow key that it parsed from the packet. Userspace then extracts its
+own notion of a flow key from the packet and compares it against the
+kernel-provided version:
+
+ - If userspace's notion of the flow key for the packet matches the
+ kernel's, then nothing special is necessary.
+
+ - If the kernel's flow key includes more fields than the userspace
+ version of the flow key, for example if the kernel decoded IPv6
+ headers but userspace stopped at the Ethernet type (because it
+ does not understand IPv6), then again nothing special is
+ necessary. Userspace can still set up a flow in the usual way,
+ as long as it uses the kernel-provided flow key to do it.
+
+ - If the userspace flow key includes more fields than the
+ kernel's, for example if userspace decoded an IPv6 header but
+ the kernel stopped at the Ethernet type, then userspace can
+ forward the packet manually, without setting up a flow in the
+ kernel. This case is bad for performance because every packet
+ that the kernel considers part of the flow must go to userspace,
+ but the forwarding behavior is correct. (If userspace can
+ determine that the values of the extra fields would not affect
+ forwarding behavior, then it could set up a flow anyway.)
+
+How flow keys evolve over time is important to making this work, so
+the following sections go into detail.
+
+
+Flow key format
+---------------
+
+A flow key is passed over a Netlink socket as a sequence of Netlink
+attributes. Some attributes represent packet metadata, defined as any
+information about a packet that cannot be extracted from the packet
+itself, e.g. the vport on which the packet was received. Most
+attributes, however, are extracted from headers within the packet,
+e.g. source and destination addresses from Ethernet, IP, or TCP
+headers.
+
+The <linux/openvswitch.h> header file defines the exact format of the
+flow key attributes. For informal explanatory purposes here, we write
+them as comma-separated strings, with parentheses indicating arguments
+and nesting. For example, the following could represent a flow key
+corresponding to a TCP packet that arrived on vport 1:
+
+ in_port(1), eth(src=e0:91:f5:21:d0:b2, dst=00:02:e3:0f:80:a4),
+ eth_type(0x0800), ipv4(src=172.16.0.20, dst=172.18.0.52, proto=17, tos=0,
+ frag=no), tcp(src=49163, dst=80)
+
+Often we ellipsize arguments not important to the discussion, e.g.:
+
+ in_port(1), eth(...), eth_type(0x0800), ipv4(...), tcp(...)
+
+
+Basic rule for evolving flow keys
+---------------------------------
+
+Some care is needed to really maintain forward and backward
+compatibility for applications that follow the rules listed under
+"Flow key compatibility" above.
+
+The basic rule is obvious:
+
+ ------------------------------------------------------------------
+ New network protocol support must only supplement existing flow
+ key attributes. It must not change the meaning of already defined
+ flow key attributes.
+ ------------------------------------------------------------------
+
+This rule does have less-obvious consequences so it is worth working
+through a few examples. Suppose, for example, that the kernel module
+did not already implement VLAN parsing. Instead, it just interpreted
+the 802.1Q TPID (0x8100) as the Ethertype then stopped parsing the
+packet. The flow key for any packet with an 802.1Q header would look
+essentially like this, ignoring metadata:
+
+ eth(...), eth_type(0x8100)
+
+Naively, to add VLAN support, it makes sense to add a new "vlan" flow
+key attribute to contain the VLAN tag, then continue to decode the
+encapsulated headers beyond the VLAN tag using the existing field
+definitions. With this change, an TCP packet in VLAN 10 would have a
+flow key much like this:
+
+ eth(...), vlan(vid=10, pcp=0), eth_type(0x0800), ip(proto=6, ...), tcp(...)
+
+But this change would negatively affect a userspace application that
+has not been updated to understand the new "vlan" flow key attribute.
+The application could, following the flow compatibility rules above,
+ignore the "vlan" attribute that it does not understand and therefore
+assume that the flow contained IP packets. This is a bad assumption
+(the flow only contains IP packets if one parses and skips over the
+802.1Q header) and it could cause the application's behavior to change
+across kernel versions even though it follows the compatibility rules.
+
+The solution is to use a set of nested attributes. This is, for
+example, why 802.1Q support uses nested attributes. A TCP packet in
+VLAN 10 is actually expressed as:
+
+ eth(...), eth_type(0x8100), vlan(vid=10, pcp=0), encap(eth_type(0x0800),
+ ip(proto=6, ...), tcp(...)))
+
+Notice how the "eth_type", "ip", and "tcp" flow key attributes are
+nested inside the "encap" attribute. Thus, an application that does
+not understand the "vlan" key will not see either of those attributes
+and therefore will not misinterpret them. (Also, the outer eth_type
+is still 0x8100, not changed to 0x0800.)
+
+Handling malformed packets
+--------------------------
+
+Don't drop packets in the kernel for malformed protocol headers, bad
+checksums, etc. This would prevent userspace from implementing a
+simple Ethernet switch that forwards every packet.
+
+Instead, in such a case, include an attribute with "empty" content.
+It doesn't matter if the empty content could be valid protocol values,
+as long as those values are rarely seen in practice, because userspace
+can always forward all packets with those values to userspace and
+handle them individually.
+
+For example, consider a packet that contains an IP header that
+indicates protocol 6 for TCP, but which is truncated just after the IP
+header, so that the TCP header is missing. The flow key for this
+packet would include a tcp attribute with all-zero src and dst, like
+this:
+
+ eth(...), eth_type(0x0800), ip(proto=6, ...), tcp(src=0, dst=0)
+
+As another example, consider a packet with an Ethernet type of 0x8100,
+indicating that a VLAN TCI should follow, but which is truncated just
+after the Ethernet type. The flow key for this packet would include
+an all-zero-bits vlan and an empty encap attribute, like this:
+
+ eth(...), eth_type(0x8100), vlan(0), encap()
+
+Unlike a TCP packet with source and destination ports 0, an
+all-zero-bits VLAN TCI is not that rare, so the CFI bit (aka
+VLAN_TAG_PRESENT inside the kernel) is ordinarily set in a vlan
+attribute expressly to allow this situation to be distinguished.
+Thus, the flow key in this second example unambiguously indicates a
+missing or malformed VLAN TCI.
+
+Other rules
+-----------
+
+The other rules for flow keys are much less subtle:
+
+ - Duplicate attributes are not allowed at a given nesting level.
+
+ - Ordering of attributes is not significant.
+
+ - When the kernel sends a given flow key to userspace, it always
+ composes it the same way. This allows userspace to hash and
+ compare entire flow keys that it may not be able to fully
+ interpret.

+
+/*
+ * The CC770 is a CAN controller from Bosch, which is 100% compatible
+ * with the AN82527 from Intel, but with "bugs" being fixed and some
+ * additional functionality, mainly:
+ *
+ * 1. RX and TX error counters are readable.
+ * 2. Support of silent (listen-only) mode.
+ * 3. Message object 15 can receive all types of frames, also RTR and EFF.
+ *
+ * Details are available from Bosch's "CC770_Product_Info_2007-01.pdf",
+ * which explains in detail the compatibility between the CC770 and the
+ * 82527. This driver use the additional functionality 3. on real CC770
+ * devices. Unfortunately, the CC770 does still not store the message
+ * identifier of received remote transmission request frames and
+ * therefore it's set to 0.
+ *
+ * The message objects 1..14 can be used for TX and RX while the message
+ * objects 15 is optimized for RX. It has a shadow register for reliable
+ * data receiption under heavy bus load. Therefore it makes sense to use
+ * this message object for the needed use case. The frame type (EFF/SFF)
+ * for the message object 15 can be defined via kernel module parameter
+ * "msgobj15_eff". If not equal 0, it will receive 29-bit EFF frames,
+ * otherwise 11 bit SFF messages.

+ * Bosch CC770 and Intel AN82527 CAN controllers on the ISA or PC-104 bus.
+ * The I/O port or memory address and the IRQ number must be specified via
+ * module parameters:
+ *
+ * insmod cc770_isa.ko port=0x310,0x380 irq=7,11
+ *
+ * for ISA devices using I/O ports or:
+ *
+ * insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11
+ *
+ * for memory mapped ISA devices.
+ *
+ * Indirect access via address and data port is supported as well:
+ *
+ * insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11
+ *
+ * Furthermore, the following mode parameter can be defined:
+ *
+ * clk: External oscillator clock frequency (default=16000000 [16 MHz])
+ * cir: CPU interface register (default=0x40 [DSC])
+ * bcr: Bus configuration register (default=0x40 [CBY])
+ * cor: Clockout register (default=0x00)
+ *
+ * Note: for clk, cir, bcr and cor, the first argument re-defines the
+ * default for all other devices, e.g.:
+ *
+ * insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000
+ *
+ * is equivalent to
+ *
+ * insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000

+ ---help---
+ Only one port is active at a time and the rest of ports are used
+ for backup.
+
+ Mac addresses of ports are not modified. Userspace is responsible
+ to do so.
+
+ To compile this team mode as a module, choose M here: the module
+ will be called team_mode_activebackup.

+ * DOC: Antenna control
+ *
+ * Hw supports up to 14 antennas ! I haven't found any card that implements
+ * that. The maximum number of antennas I've seen is up to 4 (2 for 2GHz and 2
+ * for 5GHz). Antenna 1 (MAIN) should be omnidirectional, 2 (AUX)
+ * omnidirectional or sectorial and antennas 3-14 sectorial (or directional).
+ *
+ * We can have a single antenna for RX and multiple antennas for TX.
+ * RX antenna is our "default" antenna (usually antenna 1) set on
+ * DEFAULT_ANTENNA register and TX antenna is set on each TX control descriptor
+ * (0 for automatic selection, 1 - 14 antenna number).
+ *
+ * We can let hw do all the work doing fast antenna diversity for both
+ * tx and rx or we can do things manually. Here are the options we have
+ * (all are bits of STA_ID1 register):
+ *
+ * AR5K_STA_ID1_DEFAULT_ANTENNA -> When 0 is set as the TX antenna on TX
+ * control descriptor, use the default antenna to transmit or else use the last
+ * antenna on which we received an ACK.
+ *
+ * AR5K_STA_ID1_DESC_ANTENNA -> Update default antenna after each TX frame to
+ * the antenna on which we got the ACK for that frame.
+ *
+ * AR5K_STA_ID1_RTS_DEF_ANTENNA -> Use default antenna for RTS or else use the
+ * one on the TX descriptor.
+ *
+ * AR5K_STA_ID1_SELFGEN_DEF_ANT -> Use default antenna for self generated frames
+ * (ACKs etc), or else use current antenna (the one we just used for TX).
+ *
+ * Using the above we support the following scenarios:
+ *
+ * AR5K_ANTMODE_DEFAULT -> Hw handles antenna diversity etc automatically
+ *
+ * AR5K_ANTMODE_FIXED_A -> Only antenna A (MAIN) is present
+ *
+ * AR5K_ANTMODE_FIXED_B -> Only antenna B (AUX) is present
+ *
+ * AR5K_ANTMODE_SINGLE_AP -> Sta locked on a single ap
+ *
+ * AR5K_ANTMODE_SECTOR_AP -> AP with tx antenna set on tx desc
+ *
+ * AR5K_ANTMODE_SECTOR_STA -> STA with tx antenna set on tx desc
+ *

+ * based on TSF etc), DCU adds backoff, IFSes etc and then a scheduler

+/*
+ * Rx theory of operation
+ *
+ * The host allocates 32 DMA target addresses and passes the host address
+ * to the firmware at register IL_RFDS_TBL_LOWER + N * RFD_SIZE where N is
+ * 0 to 31
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two idx registers for managing the Rx buffers.
+ *
+ * The READ idx maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ idx is managed by the firmware once the card is enabled.
+ *
+ * The WRITE idx maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * IDX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ idx
+ * and fire the RX interrupt. The driver can then query the READ idx and
+ * process as many packets as possible, moving the WRITE idx forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
+ * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replenish the iwl->rxq->rx_free.
+ * + In il3945_rx_replenish (scheduled) if 'processed' != 'read' then the
+ * iwl->rxq is replenished and the READ IDX is updated (updating the
+ * 'processed' and 'read' driver idxes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the iwl->rxq. The driver 'processed' idx is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ * IDX is not incremented and iwl->status(RX_STALLED) is set. If there
+ * were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * il3945_rx_replenish() Replenishes rx_free list from rx_used, and calls
+ * il3945_rx_queue_restock
+ * il3945_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE idx. If insufficient rx_free buffers
+ * are available, schedules il3945_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - il3945_rx() Detach il_rx_bufs from pool up to the
+ * READ IDX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls il3945_rx_queue_restock to refill any empty

+ * notifies host via "initialize alive" that it is complete.
+ *
+ * The host then replaces the BSM_DRAM_* pointer values to point to the
+ * normal runtime uCode instructions and a backup uCode data cache buffer
+ * (filled initially with starting data values for the on-board processor),
+ * then triggers the "initialize" uCode to load and launch the runtime uCode,
+ * which begins normal operation.
+ *
+ * When doing a power-save shutdown, runtime uCode saves data SRAM into
+ * the backup data cache in DRAM before SRAM is powered down.

+ * up after power-saving sleeps (or during initial uCode load), the BSM loads
+ * the bootstrap program into the on-board processor, and starts it.
+ *
+ * The bootstrap program loads (via DMA) instructions and data for a new
+ * program from host DRAM locations indicated by the host driver in the
+ * BSM_DRAM_* registers. Once the new program is loaded, it starts
+ * automatically.
+ *
+ * When initializing the NIC, the host driver points the BSM to the
+ * "initialize" uCode image. This uCode sets up some internal data, then
+ * notifies host via "initialize alive" that it is complete.
+ *
+ * The host then replaces the BSM_DRAM_* pointer values to point to the
+ * normal runtime uCode instructions and a backup uCode data cache buffer
+ * (filled initially with starting data values for the on-board processor),
+ * then triggers the "initialize" uCode to load and launch the runtime uCode,
+ * which begins normal operation.
+ *
+ * When doing a power-save shutdown, runtime uCode saves data SRAM into
+ * the backup data cache in DRAM before SRAM is powered down.
+ *
+ * When powering back up, the BSM loads the bootstrap program. This reloads
+ * the runtime uCode instructions and the backup data cache into SRAM,
+ * and re-launches the runtime uCode from where it left off.

+/**
+ * To calculate a txpower setting for a given desired target txpower, channel,
+ * modulation bit rate, and transmitter chain (4965 has 2 transmitters to
+ * support MIMO and transmit diversity), driver must do the following:
+ *
+ * 1) Compare desired txpower vs. (EEPROM) regulatory limit for this channel.
+ * Do not exceed regulatory limit; reduce target txpower if necessary.
+ *
+ * If setting up txpowers for MIMO rates (rate idxes 8-15, 24-31),
+ * 2 transmitters will be used simultaneously; driver must reduce the
+ * regulatory limit by 3 dB (half-power) for each transmitter, so the
+ * combined total output of the 2 transmitters is within regulatory limits.
+ *
+ *
+ * 2) Compare target txpower vs. (EEPROM) saturation txpower *reduced by
+ * backoff for this bit rate*. Do not exceed (saturation - backoff[rate]);
+ * reduce target txpower if necessary.
+ *
+ * Backoff values below are in 1/2 dB units (equivalent to steps in
+ * txpower gain tables):
+ *
+ * OFDM 6 - 36 MBit: 10 steps (5 dB)
+ * OFDM 48 MBit: 15 steps (7.5 dB)
+ * OFDM 54 MBit: 17 steps (8.5 dB)
+ * OFDM 60 MBit: 20 steps (10 dB)
+ * CCK all rates: 10 steps (5 dB)
+ *
+ * Backoff values apply to saturation txpower on a per-transmitter basis;
+ * when using MIMO (2 transmitters), each transmitter uses the same
+ * saturation level provided in EEPROM, and the same backoff values;
+ * no reduction (such as with regulatory txpower limits) is required.
+ *
+ * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel
+ * widths and 40 Mhz (.11n HT40) channel widths; there is no separate
+ * factory measurement for ht40 channels.
+ *
+ * The result of this step is the final target txpower. The rest of
+ * the steps figure out the proper settings for the device to achieve
+ * that target txpower.
+ *
+ *
+ * 3) Determine (EEPROM) calibration sub band for the target channel, by
+ * comparing against first and last channels in each sub band
+ * (see struct il4965_eeprom_calib_subband_info).
+ *
+ *
+ * 4) Linearly interpolate (EEPROM) factory calibration measurement sets,
+ * referencing the 2 factory-measured (sample) channels within the sub band.
+ *
+ * Interpolation is based on difference between target channel's frequency
+ * and the sample channels' frequencies. Since channel numbers are based
+ * on frequency (5 MHz between each channel number), this is equivalent
+ * to interpolating based on channel number differences.
+ *
+ * Note that the sample channels may or may not be the channels at the
+ * edges of the sub band. The target channel may be "outside" of the
+ * span of the sampled channels.
+ *
+ * Driver may choose the pair (for 2 Tx chains) of measurements (see
+ * struct il4965_eeprom_calib_ch_info) for which the actual measured
+ * txpower comes closest to the desired txpower. Usually, though,
+ * the middle set of measurements is closest to the regulatory limits,
+ * and is therefore a good choice for all txpower calculations (this
+ * assumes that high accuracy is needed for maximizing legal txpower,
+ * while lower txpower configurations do not need as much accuracy).
+ *
+ * Driver should interpolate both members of the chosen measurement pair,
+ * i.e. for both Tx chains (radio transmitters), unless the driver knows
+ * that only one of the chains will be used (e.g. only one tx antenna
+ * connected, but this should be unusual). The rate scaling algorithm
+ * switches antennas to find best performance, so both Tx chains will
+ * be used (although only one at a time) even for non-MIMO transmissions.
+ *
+ * Driver should interpolate factory values for temperature, gain table
+ * idx, and actual power. The power amplifier detector values are
+ * not used by the driver.
+ *
+ * Sanity check: If the target channel happens to be one of the sample
+ * channels, the results should agree with the sample channel's
+ * measurements!
+ *
+ *
+ * 5) Find difference between desired txpower and (interpolated)
+ * factory-measured txpower. Using (interpolated) factory gain table idx
+ * (shown elsewhere) as a starting point, adjust this idx lower to
+ * increase txpower, or higher to decrease txpower, until the target
+ * txpower is reached. Each step in the gain table is 1/2 dB.
+ *
+ * For example, if factory measured txpower is 16 dBm, and target txpower
+ * is 13 dBm, add 6 steps to the factory gain idx to reduce txpower
+ * by 3 dB.
+ *
+ *
+ * 6) Find difference between current device temperature and (interpolated)
+ * factory-measured temperature for sub-band. Factory values are in
+ * degrees Celsius. To calculate current temperature, see comments for
+ * "4965 temperature calculation".
+ *
+ * If current temperature is higher than factory temperature, driver must
+ * increase gain (lower gain table idx), and vice verse.
+ *
+ * Temperature affects gain differently for different channels:
+ *
+ * 2.4 GHz all channels: 3.5 degrees per half-dB step
+ * 5 GHz channels 34-43: 4.5 degrees per half-dB step
+ * 5 GHz channels >= 44: 4.0 degrees per half-dB step
+ *
+ * NOTE: Temperature can increase rapidly when transmitting, especially
+ * with heavy traffic at high txpowers. Driver should update
+ * temperature calculations often under these conditions to
+ * maintain strong txpower in the face of rising temperature.
+ *
+ *
+ * 7) Find difference between current power supply voltage indicator
+ * (from "initialize alive") and factory-measured power supply voltage
+ * indicator (EEPROM).
+ *
+ * If the current voltage is higher (indicator is lower) than factory
+ * voltage, gain should be reduced (gain table idx increased) by:
+ *
+ * (eeprom - current) / 7
+ *
+ * If the current voltage is lower (indicator is higher) than factory
+ * voltage, gain should be increased (gain table idx decreased) by:
+ *
+ * 2 * (current - eeprom) / 7
+ *
+ * If number of idx steps in either direction turns out to be > 2,
+ * something is wrong ... just use 0.
+ *
+ * NOTE: Voltage compensation is independent of band/channel.
+ *
+ * NOTE: "Initialize" uCode measures current voltage, which is assumed
+ * to be constant after this initial measurement. Voltage
+ * compensation for txpower (number of steps in gain table)
+ * may be calculated once and used until the next uCode bootload.
+ *
+ *
+ * 8) If setting up txpowers for MIMO rates (rate idxes 8-15, 24-31),
+ * adjust txpower for each transmitter chain, so txpower is balanced
+ * between the two chains. There are 5 pairs of tx_atten[group][chain]
+ * values in "initialize alive", one pair for each of 5 channel ranges:
+ *
+ * Group 0: 5 GHz channel 34-43
+ * Group 1: 5 GHz channel 44-70
+ * Group 2: 5 GHz channel 71-124
+ * Group 3: 5 GHz channel 125-200
+ * Group 4: 2.4 GHz all channels
+ *
+ * Add the tx_atten[group][chain] value to the idx for the target chain.
+ * The values are signed, but are in pairs of 0 and a non-negative number,
+ * so as to reduce gain (if necessary) of the "hotter" channel. This
+ * avoids any need to double-check for regulatory compliance after
+ * this step.
+ *
+ *
+ * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation
+ * value to the idx:
+ *
+ * Hardware rev B: 9 steps (4.5 dB)
+ * Hardware rev C: 5 steps (2.5 dB)
+ *
+ * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG,
+ * bits [3:2], 1 = B, 2 = C.
+ *
+ * NOTE: This compensation is in addition to any saturation backoff that
+ * might have been applied in an earlier step.
+ *
+ *
+ * 10) Select the gain table, based on band (2.4 vs 5 GHz).
+ *
+ * Limit the adjusted idx to stay within the table!
+ *
+ *
+ * 11) Read gain table entries for DSP and radio gain, place into appropriate
+ * location(s) in command (struct il4965_txpowertable_cmd).

+ * Rx SRAM Control and Status Registers (RSCSR)
+ *
+ * These registers provide handshake between driver and 4965 for the Rx queue
+ * (this queue handles *all* command responses, notifications, Rx data, etc.
+ * sent from 4965 uCode to host driver). Unlike Tx, there is only one Rx
+ * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can
+ * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
+ * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
+ * mapping between RBDs and RBs.
+ *
+ * Driver must allocate host DRAM memory for the following, and set the
+ * physical address of each into 4965 registers:
+ *
+ * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
+ * entries (although any power of 2, up to 4096, is selectable by driver).
+ * Each entry (1 dword) points to a receive buffer (RB) of consistent size
+ * (typically 4K, although 8K or 16K are also selectable by driver).
+ * Driver sets up RB size and number of RBDs in the CB via Rx config
+ * register FH49_MEM_RCSR_CHNL0_CONFIG_REG.
+ *
+ * Bit fields within one RBD:
+ * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned
+ *
+ * Driver sets physical address [35:8] of base of RBD circular buffer
+ * into FH49_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
+ *
+ * 2) Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers
+ * (RBs) have been filled, via a "write pointer", actually the idx of
+ * the RB's corresponding RBD within the circular buffer. Driver sets
+ * physical address [35:4] into FH49_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
+ *
+ * Bit fields in lower dword of Rx status buffer (upper dword not used
+ * by driver; see struct il4965_shared, val0):
+ * 31-12: Not used by driver
+ * 11- 0: Index of last filled Rx buffer descriptor
+ * (4965 writes, driver reads this value)
+ *
+ * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
+ * enter pointers to these RBs into contiguous RBD circular buffer entries,
+ * and update the 4965's "write" idx register,
+ * FH49_RSCSR_CHNL0_RBDCB_WPTR_REG.
+ *
+ * This "write" idx corresponds to the *next* RBD that the driver will make
+ * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
+ * the circular buffer. This value should initially be 0 (before preparing any
+ * RBs), should be 8 after preparing the first 8 RBs (for example), and must
+ * wrap back to 0 at the end of the circular buffer (but don't wrap before
+ * "read" idx has advanced past 1! See below).
+ * NOTE: 4965 EXPECTS THE WRITE IDX TO BE INCREMENTED IN MULTIPLES OF 8.
+ *
+ * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
+ * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
+ * to tell the driver the idx of the latest filled RBD. The driver must
+ * read this "read" idx from DRAM after receiving an Rx interrupt from 4965.
+ *
+ * The driver must also internally keep track of a third idx, which is the
+ * next RBD to process. When receiving an Rx interrupt, driver should process
+ * all filled but unprocessed RBs up to, but not including, the RB
+ * corresponding to the "read" idx. For example, if "read" idx becomes "1",
+ * driver may process the RB pointed to by RBD 0. Depending on volume of
+ * traffic, there may be many RBs to process.
+ *
+ * If read idx == write idx, 4965 thinks there is no room to put new data.
+ * Due to this, the maximum number of filled RBs is 255, instead of 256. To
+ * be safe, make sure that there is a gap of at least 2 RBDs between "write"
+ * and "read" idxes; that is, make sure that there are no more than 254
+ * buffers waiting to be filled.

- depends on EVENT_TRACING
- help
- Say Y here to trace all commands, including TX frames and IO
- accesses, sent to the device. If you say yes, iwlwifilegacy will
- register with the ftrace framework for event tracing and dump
- all this information to the ringbuffer, you may need to
- increase the ringbuffer size. See the ftrace documentation
- for more information.
-
- When tracing is not enabled, this option still has some
- (though rather small) overhead.
-
- If unsure, say Y so we can help you better when problems
- occur.

+/************************** EEPROM BANDS ****************************
+ *
+ * The il_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, il_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into il->channel_info_24/52 and il->channel_map_24/52
+ *
+ * channel_map_24/52 provides the idx in the channel_info array for a
+ * given channel. We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware. This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel. There is no corresponding channel information for that
+ * entry.

+/*
+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC. These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC. The driver and NIC manage the Rx buffers by means
+ * of idxes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two idx registers for managing the Rx buffers.
+ *
+ * The READ idx maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ idx is managed by the firmware once the card is enabled.
+ *
+ * The WRITE idx maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * IDX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ idx
+ * and fire the RX interrupt. The driver can then query the READ idx and
+ * process as many packets as possible, moving the WRITE idx forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
+ * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replenish the iwl->rxq->rx_free.
+ * + In il_rx_replenish (scheduled) if 'processed' != 'read' then the
+ * iwl->rxq is replenished and the READ IDX is updated (updating the
+ * 'processed' and 'read' driver idxes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the iwl->rxq. The driver 'processed' idx is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ * IDX is not incremented and iwl->status(RX_STALLED) is set. If there
+ * were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * il_rx_queue_alloc() Allocates rx_free
+ * il_rx_replenish() Replenishes rx_free list from rx_used, and calls
+ * il_rx_queue_restock
+ * il_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE idx. If insufficient rx_free buffers
+ * are available, schedules il_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - il_rx() Detach il_rx_bufs from pool up to the
+ * READ IDX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls il_rx_queue_restock to refill any empty

+ * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty

+ *
+ * The device reads or writes the data in the queues via the device's several

+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing

+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,

- * BSM operation:
- *
- * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
- * in special SRAM that does not power down during RFKILL. When powering back
- * up after power-saving sleeps (or during initial uCode load), the BSM loads
- * the bootstrap program into the on-board processor, and starts it.
- *
- * The bootstrap program loads (via DMA) instructions and data for a new
- * program from host DRAM locations indicated by the host driver in the
- * BSM_DRAM_* registers. Once the new program is loaded, it starts
- * automatically.
- *
- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image. This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program. This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,
- * and re-launches the runtime uCode from where it left off.

-/**
- * To calculate a txpower setting for a given desired target txpower, channel,
- * modulation bit rate, and transmitter chain (4965 has 2 transmitters to
- * support MIMO and transmit diversity), driver must do the following:
- *
- * 1) Compare desired txpower vs. (EEPROM) regulatory limit for this channel.
- * Do not exceed regulatory limit; reduce target txpower if necessary.
- *
- * If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31),
- * 2 transmitters will be used simultaneously; driver must reduce the
- * regulatory limit by 3 dB (half-power) for each transmitter, so the
- * combined total output of the 2 transmitters is within regulatory limits.
- *
- *
- * 2) Compare target txpower vs. (EEPROM) saturation txpower *reduced by
- * backoff for this bit rate*. Do not exceed (saturation - backoff[rate]);
- * reduce target txpower if necessary.
- *
- * Backoff values below are in 1/2 dB units (equivalent to steps in
- * txpower gain tables):
- *
- * OFDM 6 - 36 MBit: 10 steps (5 dB)
- * OFDM 48 MBit: 15 steps (7.5 dB)
- * OFDM 54 MBit: 17 steps (8.5 dB)
- * OFDM 60 MBit: 20 steps (10 dB)
- * CCK all rates: 10 steps (5 dB)
- *
- * Backoff values apply to saturation txpower on a per-transmitter basis;
- * when using MIMO (2 transmitters), each transmitter uses the same
- * saturation level provided in EEPROM, and the same backoff values;
- * no reduction (such as with regulatory txpower limits) is required.
- *
- * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel
- * widths and 40 Mhz (.11n HT40) channel widths; there is no separate
- * factory measurement for ht40 channels.
- *
- * The result of this step is the final target txpower. The rest of
- * the steps figure out the proper settings for the device to achieve
- * that target txpower.
- *
- *
- * 3) Determine (EEPROM) calibration sub band for the target channel, by
- * comparing against first and last channels in each sub band
- * (see struct iwl4965_eeprom_calib_subband_info).
- *
- *
- * 4) Linearly interpolate (EEPROM) factory calibration measurement sets,
- * referencing the 2 factory-measured (sample) channels within the sub band.
- *
- * Interpolation is based on difference between target channel's frequency
- * and the sample channels' frequencies. Since channel numbers are based
- * on frequency (5 MHz between each channel number), this is equivalent
- * to interpolating based on channel number differences.
- *
- * Note that the sample channels may or may not be the channels at the
- * edges of the sub band. The target channel may be "outside" of the
- * span of the sampled channels.
- *
- * Driver may choose the pair (for 2 Tx chains) of measurements (see
- * struct iwl4965_eeprom_calib_ch_info) for which the actual measured
- * txpower comes closest to the desired txpower. Usually, though,
- * the middle set of measurements is closest to the regulatory limits,
- * and is therefore a good choice for all txpower calculations (this
- * assumes that high accuracy is needed for maximizing legal txpower,
- * while lower txpower configurations do not need as much accuracy).
- *
- * Driver should interpolate both members of the chosen measurement pair,
- * i.e. for both Tx chains (radio transmitters), unless the driver knows
- * that only one of the chains will be used (e.g. only one tx antenna
- * connected, but this should be unusual). The rate scaling algorithm
- * switches antennas to find best performance, so both Tx chains will
- * be used (although only one at a time) even for non-MIMO transmissions.
- *
- * Driver should interpolate factory values for temperature, gain table
- * index, and actual power. The power amplifier detector values are
- * not used by the driver.
- *
- * Sanity check: If the target channel happens to be one of the sample
- * channels, the results should agree with the sample channel's
- * measurements!
- *
- *
- * 5) Find difference between desired txpower and (interpolated)
- * factory-measured txpower. Using (interpolated) factory gain table index
- * (shown elsewhere) as a starting point, adjust this index lower to
- * increase txpower, or higher to decrease txpower, until the target
- * txpower is reached. Each step in the gain table is 1/2 dB.
- *
- * For example, if factory measured txpower is 16 dBm, and target txpower
- * is 13 dBm, add 6 steps to the factory gain index to reduce txpower
- * by 3 dB.
- *
- *
- * 6) Find difference between current device temperature and (interpolated)
- * factory-measured temperature for sub-band. Factory values are in
- * degrees Celsius. To calculate current temperature, see comments for
- * "4965 temperature calculation".
- *
- * If current temperature is higher than factory temperature, driver must
- * increase gain (lower gain table index), and vice verse.
- *
- * Temperature affects gain differently for different channels:
- *
- * 2.4 GHz all channels: 3.5 degrees per half-dB step
- * 5 GHz channels 34-43: 4.5 degrees per half-dB step
- * 5 GHz channels >= 44: 4.0 degrees per half-dB step
- *
- * NOTE: Temperature can increase rapidly when transmitting, especially
- * with heavy traffic at high txpowers. Driver should update
- * temperature calculations often under these conditions to
- * maintain strong txpower in the face of rising temperature.
- *
- *
- * 7) Find difference between current power supply voltage indicator
- * (from "initialize alive") and factory-measured power supply voltage
- * indicator (EEPROM).
- *
- * If the current voltage is higher (indicator is lower) than factory
- * voltage, gain should be reduced (gain table index increased) by:
- *
- * (eeprom - current) / 7
- *
- * If the current voltage is lower (indicator is higher) than factory
- * voltage, gain should be increased (gain table index decreased) by:
- *
- * 2 * (current - eeprom) / 7
- *
- * If number of index steps in either direction turns out to be > 2,
- * something is wrong ... just use 0.
- *
- * NOTE: Voltage compensation is independent of band/channel.
- *
- * NOTE: "Initialize" uCode measures current voltage, which is assumed
- * to be constant after this initial measurement. Voltage
- * compensation for txpower (number of steps in gain table)
- * may be calculated once and used until the next uCode bootload.
- *
- *
- * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31),
- * adjust txpower for each transmitter chain, so txpower is balanced
- * between the two chains. There are 5 pairs of tx_atten[group][chain]
- * values in "initialize alive", one pair for each of 5 channel ranges:
- *
- * Group 0: 5 GHz channel 34-43
- * Group 1: 5 GHz channel 44-70
- * Group 2: 5 GHz channel 71-124
- * Group 3: 5 GHz channel 125-200
- * Group 4: 2.4 GHz all channels
- *
- * Add the tx_atten[group][chain] value to the index for the target chain.
- * The values are signed, but are in pairs of 0 and a non-negative number,
- * so as to reduce gain (if necessary) of the "hotter" channel. This
- * avoids any need to double-check for regulatory compliance after
- * this step.
- *
- *
- * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation
- * value to the index:
- *
- * Hardware rev B: 9 steps (4.5 dB)
- * Hardware rev C: 5 steps (2.5 dB)
- *
- * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG,
- * bits [3:2], 1 = B, 2 = C.
- *
- * NOTE: This compensation is in addition to any saturation backoff that
- * might have been applied in an earlier step.
- *
- *
- * 10) Select the gain table, based on band (2.4 vs 5 GHz).
- *
- * Limit the adjusted index to stay within the table!
- *
- *
- * 11) Read gain table entries for DSP and radio gain, place into appropriate
- * location(s) in command (struct iwl4965_txpowertable_cmd).

- * controller (uCode) are via the command queue (one of the Tx queues). All
- * uCode command responses/replies/notifications, including Rx frames, are
- * conveyed from uCode to driver via the Rx queue.
- *
- * Most support for these queues, including handshake support, resides in
- * structures in host DRAM, shared between the driver and the device. When
- * allocating this memory, the driver must make sure that data written by
- * the host CPU updates DRAM immediately (and does not get "stuck" in CPU's
- * cache memory), so DRAM and cache are consistent, and the device can
- * immediately see changes made by the driver.
- *
- * 4965 supports up to 16 DRAM-based Tx queues, and services these queues via
- * up to 7 DMA channels (FIFOs). Each Tx queue is supported by a circular array
- * in DRAM containing 256 Transmit Frame Descriptors (TFDs).

- * duplicate the first 64 entries (to avoid wrap-around within a Tx window;
- * max Tx window is 64 TFDs).
- *
- * When driver sets up a new TFD, it must also enter the total byte count
- * of the frame to be transmitted into the corresponding entry in the byte
- * count table for the chosen Tx queue. If the TFD index is 0-63, the driver

- * mac80211 queues, ACs, hardware queues, FIFOs.
- *
- * Cf. http://wireless.kernel.org/en/developers/Documentation/mac80211/queues
- *
- * Mac80211 uses the following numbers, which we get as from it
- * by way of skb_get_queue_mapping(skb):
- *
- * VO 0
- * VI 1
- * BE 2
- * BK 3
- *
- *
- * Regular (not A-MPDU) frames are put into hardware queues corresponding
- * to the FIFOs, see comments in iwl-prph.h. Aggregated frames get their
- * own queue per aggregation session (RA/TID combination), such queues are
- * set up to map into FIFOs too, for which we need an AC->FIFO mapping. In
- * order to map frames to the right queue, we also need an AC->hw queue
- * mapping. This is implemented here.
- *
- * Due to the way hw queues are set up (by the hw specific modules like
- * iwl-4965.c), the AC->hw queue mapping is the identity
- * mapping.

- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image. This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program. This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,

- * @fw_name_pre: Firmware filename prefix. The api version and extension
- * (.ucode) will be added to filename before loading from disk. The
- * filename is constructed as fw_name_pre<api>.ucode.
- * @ucode_api_max: Highest version of uCode API supported by driver.
- * @ucode_api_min: Lowest version of uCode API supported by driver.
- * @scan_antennas: available antenna for scan operation
- * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
- *
- * We enable the driver to be backward compatible wrt API version. The
- * driver specifies which APIs it supports (with @ucode_api_max being the
- * highest and @ucode_api_min the lowest). Firmware will only be loaded if
- * it has a supported API version. The firmware's API version will be
- * stored in @iwl_priv, enabling the driver to make runtime changes based
- * on firmware version used.
- *
- * For example,
- * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
- * Driver interacts with Firmware API version >= 2.
- * } else {
- * Driver interacts with Firmware API version 1.
- * }
- *
- * The ideal usage of this infrastructure is to treat a new ucode API
- * release as a new hardware revision. That is, through utilizing the
- * iwl_hcmd_utils_ops etc. we accommodate different command structures
- * and flows between hardware versions as well as their API
- * versions.

-/************************** EEPROM BANDS ****************************
- *
- * The iwlegacy_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel. We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware. This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel. There is no corresponding channel information for that
- * entry.

- * Rx SRAM Control and Status Registers (RSCSR)
- *
- * These registers provide handshake between driver and 4965 for the Rx queue
- * (this queue handles *all* command responses, notifications, Rx data, etc.
- * sent from 4965 uCode to host driver). Unlike Tx, there is only one Rx
- * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can
- * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
- * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
- * mapping between RBDs and RBs.
- *
- * Driver must allocate host DRAM memory for the following, and set the
- * physical address of each into 4965 registers:
- *
- * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
- * entries (although any power of 2, up to 4096, is selectable by driver).
- * Each entry (1 dword) points to a receive buffer (RB) of consistent size
- * (typically 4K, although 8K or 16K are also selectable by driver).
- * Driver sets up RB size and number of RBDs in the CB via Rx config
- * register FH_MEM_RCSR_CHNL0_CONFIG_REG.
- *
- * Bit fields within one RBD:
- * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned
- *
- * Driver sets physical address [35:8] of base of RBD circular buffer
- * into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
- *
- * 2) Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers
- * (RBs) have been filled, via a "write pointer", actually the index of
- * the RB's corresponding RBD within the circular buffer. Driver sets
- * physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
- *
- * Bit fields in lower dword of Rx status buffer (upper dword not used
- * by driver; see struct iwl4965_shared, val0):
- * 31-12: Not used by driver
- * 11- 0: Index of last filled Rx buffer descriptor
- * (4965 writes, driver reads this value)
- *
- * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
- * enter pointers to these RBs into contiguous RBD circular buffer entries,
- * and update the 4965's "write" index register,
- * FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
- *
- * This "write" index corresponds to the *next* RBD that the driver will make
- * available, i.e. one RBD past the tail of the ready-to-fill RBDs within

- * RBs), should be 8 after preparing the first 8 RBs (for example), and must
- * wrap back to 0 at the end of the circular buffer (but don't wrap before
- * "read" index has advanced past 1! See below).
- * NOTE: 4965 EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
- *
- * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
- * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
- * to tell the driver the index of the latest filled RBD. The driver must
- * read this "read" index from DRAM after receiving an Rx interrupt from 4965.
- *
- * The driver must also internally keep track of a third index, which is the
- * next RBD to process. When receiving an Rx interrupt, driver should process
- * all filled but unprocessed RBs up to, but not including, the RB
- * corresponding to the "read" index. For example, if "read" index becomes "1",
- * driver may process the RB pointed to by RBD 0. Depending on volume of
- * traffic, there may be many RBs to process.
- *
- * If read index == write index, 4965 thinks there is no room to put new data.
- * Due to this, the maximum number of filled RBs is 255, instead of 256. To
- * be safe, make sure that there is a gap of at least 2 RBDs between "write"
- * and "read" indexes; that is, make sure that there are no more than 254
- * buffers waiting to be filled.

-/*
- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC. These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC. The driver and NIC manage the Rx buffers by means
- * of indexes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt. The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
- * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- * to replenish the iwl->rxq->rx_free.
- * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
- * iwl->rxq is replenished and the READ INDEX is updated (updating the
- * 'processed' and 'read' driver indexes as well)
- * + A received packet is processed and handed to the kernel network stack,
- * detached from the iwl->rxq. The driver 'processed' index is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there
- * were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * iwl_legacy_rx_queue_alloc() Allocates rx_free
- * iwl_rx_replenish() Replenishes rx_free list from rx_used, and calls
- * iwl_rx_queue_restock
- * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
- * queue, updates firmware pointers, and updates
- * the WRITE index. If insufficient rx_free buffers
- * are available, schedules iwl_rx_replenish
- *
- * -- enable interrupts --
- * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the
- * READ INDEX, detaching the SKB from the pool.
- * Moves the packet buffer from queue to rx_used.
- * Calls iwl_rx_queue_restock to refill any empty
- * slots.

- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill. Driver and device exchange status of each
- * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels. Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.

-/************************** RX-FUNCTIONS ****************************/
-/*
- * Rx theory of operation
- *
- * The host allocates 32 DMA target addresses and passes the host address
- * to the firmware at register IWL_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
- * 0 to 31
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt. The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
- * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- * to replenish the iwl->rxq->rx_free.
- * + In iwl3945_rx_replenish (scheduled) if 'processed' != 'read' then the
- * iwl->rxq is replenished and the READ INDEX is updated (updating the
- * 'processed' and 'read' driver indexes as well)
- * + A received packet is processed and handed to the kernel network stack,
- * detached from the iwl->rxq. The driver 'processed' index is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there
- * were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * iwl3945_rx_replenish() Replenishes rx_free list from rx_used, and calls
- * iwl3945_rx_queue_restock
- * iwl3945_rx_queue_restock() Moves available buffers from rx_free into Rx
- * queue, updates firmware pointers, and updates
- * the WRITE index. If insufficient rx_free buffers
- * are available, schedules iwl3945_rx_replenish
- *
- * -- enable interrupts --
- * ISR - iwl3945_rx() Detach iwl_rx_mem_buffers from pool up to the
- * READ INDEX, detaching the SKB from the pool.
- * Moves the packet buffer from queue to rx_used.
- * Calls iwl3945_rx_queue_restock to refill any empty

+ * Dynamic queue limits (dql) - Definitions
+ *
+ * Copyright (c) 2011, Tom Herbert <therbert@google.com>
+ *
+ * This header file contains the definitions for dynamic queue limits (dql).
+ * dql would be used in conjunction with a producer/consumer type queue
+ * (possibly a HW queue). Such a queue would have these general properties:
+ *
+ * 1) Objects are queued up to some limit specified as number of objects.
+ * 2) Periodically a completion process executes which retires consumed
+ * objects.
+ * 3) Starvation occurs when limit has been reached, all queued data has
+ * actually been consumed, but completion processing has not yet run
+ * so queuing new data is blocked.
+ * 4) Minimizing the amount of queued data is desirable.
+ *
+ * The goal of dql is to calculate the limit as the minimum number of objects
+ * needed to prevent starvation.
+ *
+ * The primary functions of dql are:
+ * dql_queued - called when objects are enqueued to record number of objects
+ * dql_avail - returns how many objects are available to be queued based
+ * on the object limit and how many objects are already enqueued
+ * dql_completed - called at completion time to indicate how many objects
+ * were retired from the queue
+ *
+ * The dql implementation does not implement any locking for the dql data
+ * structures, the higher layer should provide this. dql_queued should
+ * be serialized to prevent concurrent execution of the function; this
+ * is also true for dql_completed. However, dql_queued and dlq_completed can
+ * be executed concurrently (i.e. they can be protected by different locks).

+ tristate "Open vSwitch"
+ ---help---
+ Open vSwitch is a multilayer Ethernet switch targeted at virtualized
+ environments. In addition to supporting a variety of features
+ expected in a traditional hardware switch, it enables fine-grained
+ programmatic extension and flow-based control of the network. This
+ control is useful in a wide variety of applications but is
+ particularly important in multi-server virtualization deployments,
+ which are often characterized by highly dynamic endpoints and the
+ need to maintain logical abstractions for multiple tenants.
+
+ The Open vSwitch datapath provides an in-kernel fast path for packet
+ forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
+ which is able to accept configuration from a variety of sources and
+ translate it into packet processing rules.
+
+ See http://openvswitch.org for more information and userspace
+ utilities.
+
+ To compile this code as a module, choose M here: the module will be
+ called openvswitch.
+
+ If unsure, say N.
