254 * @ucode_api_max: Highest version of uCode API supported by driver.

256 * @pa_type: used by 6000 series only to identify the type of Power Amplifier

258 * @shadow_ram_support: shadow support for OTP memory
259 * @led_compensation: compensate on the led on/off time per HW according
260 * to the deviation to achieve the desired led frequency.
261 * The detail algorithm is described in iwl-led.c
262 * @use_rts_for_aggregation: use rts/cts protection for HT traffic
263 * @chain_noise_num_beacons: number of beacons used to compute chain noise
264 * @adv_thermal_throttle: support advance thermal throttle
265 * @support_ct_kill_exit: support ct kill exit condition
266 * @support_wimax_coexist: support wimax/wifi co-exist
267 * @plcp_delta_threshold: plcp error rate threshold used to trigger
268 * radio tuning when there is a high receiving plcp error rate
269 * @chain_noise_scale: default chain noise scale used for gain computation
270 * @monitor_recover_period: default timer used to check stuck queues
271 * @temperature_kelvin: temperature report by uCode in kelvin
272 * @max_event_log_size: size of event log buffer size for ucode event logging
273 * @tx_power_by_driver: tx power calibration performed by driver
275 * @ucode_tracing: support ucode continuous tracing
276 * @sensitivity_calib_by_driver: driver has the capability to perform
277 * sensitivity calibration operation
278 * @chain_noise_calib_by_driver: driver has the capability to perform
279 * chain noise calibration operation
280 * @scan_antennas: available antenna for scan operation

282 * @need_dc_calib: need to perform init dc calibration
283 * @bt_statistics: use BT version of statistics notification
284 * @agg_time_limit: maximum number of uSec in aggregation
285 * @ampdu_factor: Maximum A-MPDU length factor
286 * @ampdu_density: Minimum A-MPDU spacing
288 * We enable the driver to be backward compatible wrt API version. The
289 * driver specifies which APIs it supports (with @ucode_api_max being the
290 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
291 * it has a supported API version. The firmware's API version will be
292 * stored in @iwl_priv, enabling the driver to make runtime changes based
293 * on firmware version used.
296 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
297 * Driver interacts with Firmware API version >= 2.
299 * Driver interacts with Firmware API version 1.
302 * The ideal usage of this infrastructure is to treat a new ucode API
303 * release as a new hardware revision. That is, through utilizing the
304 * iwl_hcmd_utils_ops etc. we accommodate different command structures
305 * and flows between hardware versions (4965/5000) as well as their API
