234 * struct iwl_cfg
235 * @fw_name_pre: Firmware filename prefix. The api version and extension
236 * (.ucode) will be added to filename before loading from disk. The
237 * filename is constructed as fw_name_pre<api>.ucode.
238 * @ucode_api_max: Highest version of uCode API supported by driver.
239 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 240 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 241 * @max_ll_items: max number of OTP blocks
242 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 243 * @led_compensation: compensate on the led on/off time per HW according
244 * to the deviation to achieve the desired led frequency.
245 * The detail algorithm is described in iwl-led.c
47eef9bd 246 * @use_rts_for_ht: use rts/cts protection for HT traffic
d8c07e7a 247 * @chain_noise_num_beacons: number of beacons used to compute chain noise
6047b4f9 248 * @adv_thermal_throttle: support advance thermal throttle
480e8407 249 * @support_ct_kill_exit: support ct kill exit condition
1933ac4d 250 * @support_wimax_coexist: support wimax/wifi co-exist
3e4fb5fa
TAN		 251 * @plcp_delta_threshold: plcp error rate threshold used to trigger
252 * radio tuning when there is a high receiving plcp error rate
4ff73974
WYG		 253 * @chain_noise_scale: default chain noise scale used for gain computation
254 * @monitor_recover_period: default timer used to check stuck queues
255 * @temperature_kelvin: temperature report by uCode in kelvin
256 * @max_event_log_size: size of event log buffer size for ucode event logging
257 * @tx_power_by_driver: tx power calibration performed by driver
258 * instead of uCode
259 * @ucode_tracing: support ucode continuous tracing
260 * @sensitivity_calib_by_driver: driver has the capability to perform
261 * sensitivity calibration operation
262 * @chain_noise_calib_by_driver: driver has the capability to perform
263 * chain noise calibration operation
264 * @scan_antennas: available antenna for scan operation
a0987a8d
RC		 265 *
266 * We enable the driver to be backward compatible wrt API version. The
267 * driver specifies which APIs it supports (with @ucode_api_max being the
268 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
269 * it has a supported API version. The firmware's API version will be
270 * stored in @iwl_priv, enabling the driver to make runtime changes based
271 * on firmware version used.
272 *
273 * For example,
274 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
275 * Driver interacts with Firmware API version >= 2.
276 * } else {
277 * Driver interacts with Firmware API version 1.
278 * }
279 *
280 * The ideal usage of this infrastructure is to treat a new ucode API
281 * release as a new hardware revision. That is, through utilizing the
282 * iwl_hcmd_utils_ops etc. we accommodate different command structures
283 * and flows between hardware versions (4965/5000) as well as their API
284 * versions.
