241 * @fw_name_pre: Firmware filename prefix. The api version and extension
242 * (.ucode) will be added to filename before loading from disk. The

244 * @ucode_api_max: Highest version of uCode API supported by driver.
245 * @ucode_api_min: Lowest version of uCode API supported by driver.
246 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
247 * @max_ll_items: max number of OTP blocks
248 * @shadow_ram_support: shadow support for OTP memory
249 * @led_compensation: compensate on the led on/off time per HW according
250 * to the deviation to achieve the desired led frequency.
251 * The detail algorithm is described in iwl-led.c
252 * @use_rts_for_ht: use rts/cts protection for HT traffic
253 * @chain_noise_num_beacons: number of beacons used to compute chain noise
254 * @adv_thermal_throttle: support advance thermal throttle
255 * @support_ct_kill_exit: support ct kill exit condition
256 * @support_wimax_coexist: support wimax/wifi co-exist
257 * @plcp_delta_threshold: plcp error rate threshold used to trigger
258 * radio tuning when there is a high receiving plcp error rate
259 * @chain_noise_scale: default chain noise scale used for gain computation
260 * @monitor_recover_period: default timer used to check stuck queues
261 * @temperature_kelvin: temperature report by uCode in kelvin
262 * @max_event_log_size: size of event log buffer size for ucode event logging
263 * @tx_power_by_driver: tx power calibration performed by driver
265 * @ucode_tracing: support ucode continuous tracing
266 * @sensitivity_calib_by_driver: driver has the capability to perform
267 * sensitivity calibration operation
268 * @chain_noise_calib_by_driver: driver has the capability to perform
269 * chain noise calibration operation
270 * @scan_antennas: available antenna for scan operation
272 * We enable the driver to be backward compatible wrt API version. The
273 * driver specifies which APIs it supports (with @ucode_api_max being the
274 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
275 * it has a supported API version. The firmware's API version will be
276 * stored in @iwl_priv, enabling the driver to make runtime changes based
277 * on firmware version used.
280 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
281 * Driver interacts with Firmware API version >= 2.
283 * Driver interacts with Firmware API version 1.
286 * The ideal usage of this infrastructure is to treat a new ucode API
287 * release as a new hardware revision. That is, through utilizing the
288 * iwl_hcmd_utils_ops etc. we accommodate different command structures
289 * and flows between hardware versions (4965/5000) as well as their API
