252 * struct iwl_cfg
253 * @fw_name_pre: Firmware filename prefix. The api version and extension
254 * (.ucode) will be added to filename before loading from disk. The
255 * filename is constructed as fw_name_pre<api>.ucode.
256 * @ucode_api_max: Highest version of uCode API supported by driver.
257 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 258 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 259 * @max_ll_items: max number of OTP blocks
260 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 261 * @led_compensation: compensate on the led on/off time per HW according
262 * to the deviation to achieve the desired led frequency.
263 * The detail algorithm is described in iwl-led.c
94597ab2 264 * @use_rts_for_aggregation: use rts/cts protection for HT traffic
d8c07e7a 265 * @chain_noise_num_beacons: number of beacons used to compute chain noise
6047b4f9 266 * @adv_thermal_throttle: support advance thermal throttle
480e8407 267 * @support_ct_kill_exit: support ct kill exit condition
1933ac4d 268 * @support_wimax_coexist: support wimax/wifi co-exist
3e4fb5fa
TAN		 269 * @plcp_delta_threshold: plcp error rate threshold used to trigger
270 * radio tuning when there is a high receiving plcp error rate
4ff73974
WYG		 271 * @chain_noise_scale: default chain noise scale used for gain computation
272 * @monitor_recover_period: default timer used to check stuck queues
273 * @temperature_kelvin: temperature report by uCode in kelvin
274 * @max_event_log_size: size of event log buffer size for ucode event logging
275 * @tx_power_by_driver: tx power calibration performed by driver
276 * instead of uCode
277 * @ucode_tracing: support ucode continuous tracing
278 * @sensitivity_calib_by_driver: driver has the capability to perform
279 * sensitivity calibration operation
280 * @chain_noise_calib_by_driver: driver has the capability to perform
281 * chain noise calibration operation
282 * @scan_antennas: available antenna for scan operation
670245ed 283 * @advanced_bt_coexist: support advanced bt coexist
a4b96cc4 284 * @bt_init_traffic_load: specify initial bt traffic load
5d297d50 285 * @bt_prio_boost: default bt priority boost value
2cbc19f3
WYG		 286 * @need_dc_calib: need to perform init dc calibration
287 * @bt_statistics: use BT version of statistics notification
7469701e 288 * @agg_time_limit: maximum number of uSec in aggregation
172c1d11
WYG		 289 * @ampdu_factor: Maximum A-MPDU length factor
290 * @ampdu_density: Minimum A-MPDU spacing
a0987a8d
RC		 291 *
292 * We enable the driver to be backward compatible wrt API version. The
293 * driver specifies which APIs it supports (with @ucode_api_max being the
294 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
295 * it has a supported API version. The firmware's API version will be
296 * stored in @iwl_priv, enabling the driver to make runtime changes based
297 * on firmware version used.
298 *
299 * For example,
300 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
301 * Driver interacts with Firmware API version >= 2.
302 * } else {
303 * Driver interacts with Firmware API version 1.
304 * }
305 *
306 * The ideal usage of this infrastructure is to treat a new ucode API
307 * release as a new hardware revision. That is, through utilizing the
308 * iwl_hcmd_utils_ops etc. we accommodate different command structures
309 * and flows between hardware versions (4965/5000) as well as their API
310 * versions.
