262 * @shadow_ram_support: shadow support for OTP memory
263 * @led_compensation: compensate on the led on/off time per HW according

265 * The detail algorithm is described in iwl-led.c
266 * @use_rts_for_aggregation: use rts/cts protection for HT traffic

268 * @adv_thermal_throttle: support advance thermal throttle
269 * @support_ct_kill_exit: support ct kill exit condition
270 * @support_wimax_coexist: support wimax/wifi co-exist
271 * @plcp_delta_threshold: plcp error rate threshold used to trigger
272 * radio tuning when there is a high receiving plcp error rate
273 * @chain_noise_scale: default chain noise scale used for gain computation
274 * @monitor_recover_period: default timer used to check stuck queues
275 * @temperature_kelvin: temperature report by uCode in kelvin
276 * @max_event_log_size: size of event log buffer size for ucode event logging
277 * @tx_power_by_driver: tx power calibration performed by driver
279 * @ucode_tracing: support ucode continuous tracing
280 * @sensitivity_calib_by_driver: driver has the capability to perform
281 * sensitivity calibration operation

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