232 * @fw_name_pre: Firmware filename prefix. The api version and extension
233 * (.ucode) will be added to filename before loading from disk. The

235 * @ucode_api_max: Highest version of uCode API supported by driver.
236 * @ucode_api_min: Lowest version of uCode API supported by driver.
237 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
238 * @max_ll_items: max number of OTP blocks
239 * @shadow_ram_support: shadow support for OTP memory
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
243 * @use_rts_for_ht: use rts/cts protection for HT traffic
244 * @chain_noise_num_beacons: number of beacons used to compute chain noise
245 * @adv_thermal_throttle: support advance thermal throttle
246 * @support_ct_kill_exit: support ct kill exit condition
247 * @support_wimax_coexist: support wimax/wifi co-exist
248 * @plcp_delta_threshold: plcp error rate threshold used to trigger
249 * radio tuning when there is a high receiving plcp error rate
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
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
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.
271 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
272 * Driver interacts with Firmware API version >= 2.
274 * Driver interacts with Firmware API version 1.
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
