| * struct iwl_cfg |
| * @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. |
| * @pa_type: used by 6000 series only to identify the type of Power Amplifier |
| * @max_ll_items: max number of OTP blocks |
| * @shadow_ram_support: shadow support for OTP memory |
| * @led_compensation: compensate on the led on/off time per HW according |
| * to the deviation to achieve the desired led frequency. |
| * The detail algorithm is described in iwl-led.c |
| * @use_rts_for_aggregation: use rts/cts protection for HT traffic |
| * @chain_noise_num_beacons: number of beacons used to compute chain noise |
| * @adv_thermal_throttle: support advance thermal throttle |
| * @support_ct_kill_exit: support ct kill exit condition |
| * @support_wimax_coexist: support wimax/wifi co-exist |
| * @plcp_delta_threshold: plcp error rate threshold used to trigger |
| * radio tuning when there is a high receiving plcp error rate |
| * @chain_noise_scale: default chain noise scale used for gain computation |
| * @monitor_recover_period: default timer used to check stuck queues |
| * @temperature_kelvin: temperature report by uCode in kelvin |
| * @max_event_log_size: size of event log buffer size for ucode event logging |
| * @tx_power_by_driver: tx power calibration performed by driver |
| * instead of uCode |
| * @ucode_tracing: support ucode continuous tracing |
| * @sensitivity_calib_by_driver: driver has the capability to perform |
| * sensitivity calibration operation |
| * @chain_noise_calib_by_driver: driver has the capability to perform |
| * chain noise calibration operation |
| * @scan_antennas: available antenna for scan operation |
| * @advanced_bt_coexist: support advanced bt coexist |
| * @bt_init_traffic_load: specify initial bt traffic load |
| * @bt_prio_boost: default bt priority boost value |
| * @need_dc_calib: need to perform init dc calibration |
| * @bt_statistics: use BT version of statistics notification |
| * @agg_time_limit: maximum number of uSec in aggregation |
| * @ampdu_factor: Maximum A-MPDU length factor |
| * @ampdu_density: Minimum A-MPDU spacing |
| * |
| * 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 (4965/5000) as well as their API |
| * versions. |
