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