+3.5 Overriding Configuration for Special Cases
+----------------------------------------------
+When using the bonding driver, the physical port which transmits a frame is
+typically selected by the bonding driver, and is not relevant to the user or
+system administrator. The output port is simply selected using the policies of
+the selected bonding mode. On occasion however, it is helpful to direct certain
+classes of traffic to certain physical interfaces on output to implement
+slightly more complex policies. For example, to reach a web server over a
+bonded interface in which eth0 connects to a private network, while eth1
+connects via a public network, it may be desirous to bias the bond to send said
+traffic over eth0 first, using eth1 only as a fall back, while all other traffic
+can safely be sent over either interface. Such configurations may be achieved
+using the traffic control utilities inherent in linux.
-4. Querying Bonding Configuration
+By default the bonding driver is multiqueue aware and 16 queues are created
+when the driver initializes (see Documentation/networking/multiqueue.txt
+for details). If more or less queues are desired the module parameter
+tx_queues can be used to change this value. There is no sysfs parameter
+available as the allocation is done at module init time.
+
+The output of the file /proc/net/bonding/bondX has changed so the output Queue
+ID is now printed for each slave:
+
+Bonding Mode: fault-tolerance (active-backup)
+Primary Slave: None
+Currently Active Slave: eth0
+MII Status: up
+MII Polling Interval (ms): 0
+Up Delay (ms): 0
+Down Delay (ms): 0
+
+Slave Interface: eth0
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cb
+Slave queue ID: 0
+
+Slave Interface: eth1
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cc
+Slave queue ID: 2
+
+The queue_id for a slave can be set using the command:
+
+# echo "eth1:2" > /sys/class/net/bond0/bonding/queue_id
+
+Any interface that needs a queue_id set should set it with multiple calls
+like the one above until proper priorities are set for all interfaces. On
+distributions that allow configuration via initscripts, multiple 'queue_id'
+arguments can be added to BONDING_OPTS to set all needed slave queues.
+
+These queue id's can be used in conjunction with the tc utility to configure
+a multiqueue qdisc and filters to bias certain traffic to transmit on certain
+slave devices. For instance, say we wanted, in the above configuration to
+force all traffic bound to 192.168.1.100 to use eth1 in the bond as its output
+device. The following commands would accomplish this:
+
+# tc qdisc add dev bond0 handle 1 root multiq
+
+# tc filter add dev bond0 protocol ip parent 1: prio 1 u32 match ip dst \
+ 192.168.1.100 action skbedit queue_mapping 2
+
+These commands tell the kernel to attach a multiqueue queue discipline to the
+bond0 interface and filter traffic enqueued to it, such that packets with a dst
+ip of 192.168.1.100 have their output queue mapping value overwritten to 2.
+This value is then passed into the driver, causing the normal output path
+selection policy to be overridden, selecting instead qid 2, which maps to eth1.
+
+Note that qid values begin at 1. Qid 0 is reserved to initiate to the driver
+that normal output policy selection should take place. One benefit to simply
+leaving the qid for a slave to 0 is the multiqueue awareness in the bonding
+driver that is now present. This awareness allows tc filters to be placed on
+slave devices as well as bond devices and the bonding driver will simply act as
+a pass-through for selecting output queues on the slave device rather than
+output port selection.
+
+This feature first appeared in bonding driver version 3.7.0 and support for
+output slave selection was limited to round-robin and active-backup modes.

+- CAIF SPI porting -
+
+- CAIF SPI basics:
+
+Running CAIF over SPI needs some extra setup, owing to the nature of SPI.
+Two extra GPIOs have been added in order to negotiate the transfers
+ between the master and the slave. The minimum requirement for running
+CAIF over SPI is a SPI slave chip and two GPIOs (more details below).
+Please note that running as a slave implies that you need to keep up
+with the master clock. An overrun or underrun event is fatal.
+
+- CAIF SPI framework:
+
+To make porting as easy as possible, the CAIF SPI has been divided in
+two parts. The first part (called the interface part) deals with all
+generic functionality such as length framing, SPI frame negotiation
+and SPI frame delivery and transmission. The other part is the CAIF
+SPI slave device part, which is the module that you have to write if
+you want to run SPI CAIF on a new hardware. This part takes care of
+the physical hardware, both with regard to SPI and to GPIOs.
+
+- Implementing a CAIF SPI device:
+
+ - Functionality provided by the CAIF SPI slave device:
+
+ In order to implement a SPI device you will, as a minimum,
+ need to implement the following
+ functions:
+
+ int (*init_xfer) (struct cfspi_xfer * xfer, struct cfspi_dev *dev):
+
+ This function is called by the CAIF SPI interface to give
+ you a chance to set up your hardware to be ready to receive
+ a stream of data from the master. The xfer structure contains
+ both physical and logical adresses, as well as the total length
+ of the transfer in both directions.The dev parameter can be used
+ to map to different CAIF SPI slave devices.
+
+ void (*sig_xfer) (bool xfer, struct cfspi_dev *dev):
+
+ This function is called by the CAIF SPI interface when the output
+ (SPI_INT) GPIO needs to change state. The boolean value of the xfer
+ variable indicates whether the GPIO should be asserted (HIGH) or
+ deasserted (LOW). The dev parameter can be used to map to different CAIF
+ SPI slave devices.
+
+ - Functionality provided by the CAIF SPI interface:
+
+ void (*ss_cb) (bool assert, struct cfspi_ifc *ifc);
+
+ This function is called by the CAIF SPI slave device in order to
+ signal a change of state of the input GPIO (SS) to the interface.
+ Only active edges are mandatory to be reported.
+ This function can be called from IRQ context (recommended in order
+ not to introduce latency). The ifc parameter should be the pointer
+ returned from the platform probe function in the SPI device structure.
+
+ void (*xfer_done_cb) (struct cfspi_ifc *ifc);
+
+ This function is called by the CAIF SPI slave device in order to
+ report that a transfer is completed. This function should only be
+ called once both the transmission and the reception are completed.
+ This function can be called from IRQ context (recommended in order
+ not to introduce latency). The ifc parameter should be the pointer
+ returned from the platform probe function in the SPI device structure.
+
+ - Connecting the bits and pieces:
+
+ - Filling in the SPI slave device structure:
+
+ Connect the necessary callback functions.
+ Indicate clock speed (used to calculate toggle delays).
+ Chose a suitable name (helps debugging if you use several CAIF
+ SPI slave devices).
+ Assign your private data (can be used to map to your structure).
+
+ - Filling in the SPI slave platform device structure:
+ Add name of driver to connect to ("cfspi_sspi").
+ Assign the SPI slave device structure as platform data.
+
+- Padding:
+
+In order to optimize throughput, a number of SPI padding options are provided.
+Padding can be enabled independently for uplink and downlink transfers.
+Padding can be enabled for the head, the tail and for the total frame size.
+The padding needs to be correctly configured on both sides of the link.
+The padding can be changed via module parameters in cfspi_sspi.c or via
+the sysfs directory of the cfspi_sspi driver (before device registration).

+-------------------------------------------------------------------------------
+
+The PACKET_TIMESTAMP setting determines the source of the timestamp in
+the packet meta information. If your NIC is capable of timestamping
+packets in hardware, you can request those hardware timestamps to used.
+Note: you may need to enable the generation of hardware timestamps with
+SIOCSHWTSTAMP.
+
+PACKET_TIMESTAMP accepts the same integer bit field as
+SO_TIMESTAMPING. However, only the SOF_TIMESTAMPING_SYS_HARDWARE
+and SOF_TIMESTAMPING_RAW_HARDWARE values are recognized by
+PACKET_TIMESTAMP. SOF_TIMESTAMPING_SYS_HARDWARE takes precedence over
+SOF_TIMESTAMPING_RAW_HARDWARE if both bits are set.
+
+ int req = 0;
+ req |= SOF_TIMESTAMPING_SYS_HARDWARE;
+ setsockopt(fd, SOL_PACKET, PACKET_TIMESTAMP, (void *) &req, sizeof(req))
+
+If PACKET_TIMESTAMP is not set, a software timestamp generated inside
+the networking stack is used (the behavior before this setting was added).
+
+See include/linux/net_tstamp.h and Documentation/networking/timestamping
+for more information on hardware timestamps.

+/*
+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ * be lost, thus blocking readers forever.
+ * If this synchronization point is not a mutex, but a spinlock or
+ * spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ * are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ * pure reads. But if they have to fetch many values, it's better to not allow
+ * preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ * (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ * read partial values)
+ *
+ * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
+ * u64_stats_fetch_retry_bh() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ * spin_lock_bh(...) or other synchronization to get exclusive access
+ * ...
+ * u64_stats_update_begin(&stats->syncp);
+ * stats->bytes64 += len; // non atomic operation
+ * stats->packets64++; // non atomic operation
+ * u64_stats_update_end(&stats->syncp);
+ *
+ * While a consumer (reader) should use following template to get consistent
+ * snapshot for each variable (but no guarantee on several ones)
+ *
+ * u64 tbytes, tpackets;
+ * unsigned int start;
+ *
+ * do {
+ * start = u64_stats_fetch_begin(&stats->syncp);
+ * tbytes = stats->bytes64; // non atomic operation
+ * tpackets = stats->packets64; // non atomic operation
+ * } while (u64_stats_fetch_retry(&stats->syncp, start));
+ *
+ *
+ * Example of use in drivers/net/loopback.c, using per_cpu containers,
+ * in BH disabled context.

+ * or device is responsible for actually aggregating the frames,
+ * as well as deciding how many and which to aggregate.
*
- * When TX aggregation is started by some subsystem (usually the rate control
- * algorithm would be appropriate) by calling the
- * ieee80211_start_tx_ba_session() function, the driver will be notified via

+ * notified via its @ampdu_action function, with the
+ * %IEEE80211_AMPDU_TX_START action.
*
* In response to that, the driver is later required to call the

- * function, which will start the aggregation session.

+ * If the peer responds negatively, the session will be stopped
+ * again right away. Note that it is possible for the aggregation
+ * session to be stopped before the driver has indicated that it
+ * is done setting it up, in which case it must not indicate the
+ * setup completion.
*
- * Similarly, when the aggregation session is stopped by
- * ieee80211_stop_tx_ba_session(), the driver's @ampdu_action function will
- * be called with the action %IEEE80211_AMPDU_TX_STOP. In this case, the
- * call must not fail, and the driver must later call ieee80211_stop_tx_ba_cb()
- * (or ieee80211_stop_tx_ba_cb_irqsafe()).
+ * Also note that, since we also need to wait for a response from

- Please note that currently this option only sets a default state.
- You may change it at boot time with nf_conntrack.acct=0/1 kernel

- You may also disable/enable it on a running system with:
- sysctl net.netfilter.nf_conntrack_acct=0/1
