230 * @fw_name_pre: Firmware filename prefix. The api version and extension
231 * (.ucode) will be added to filename before loading from disk. The
232 * filename is constructed as fw_name_pre<api>.ucode.
233 * @ucode_api_max: Highest version of uCode API supported by driver.
234 * @ucode_api_min: Lowest version of uCode API supported by driver.
235 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
236 * @max_ll_items: max number of OTP blocks
237 * @shadow_ram_support: shadow support for OTP memory
238 * @led_compensation: compensate on the led on/off time per HW according
239 * to the deviation to achieve the desired led frequency.
240 * The detail algorithm is described in iwl-led.c
241 * @use_rts_for_ht: use rts/cts protection for HT traffic
242 * @chain_noise_num_beacons: number of beacons used to compute chain noise
243 * @adv_thermal_throttle: support advance thermal throttle
244 * @support_ct_kill_exit: support ct kill exit condition

246 * @plcp_delta_threshold: plcp error rate threshold used to trigger
247 * radio tuning when there is a high receiving plcp error rate
249 * We enable the driver to be backward compatible wrt API version. The
250 * driver specifies which APIs it supports (with @ucode_api_max being the
251 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
252 * it has a supported API version. The firmware's API version will be
253 * stored in @iwl_priv, enabling the driver to make runtime changes based
254 * on firmware version used.

258 * Driver interacts with Firmware API version >= 2.
260 * Driver interacts with Firmware API version 1.
263 * The ideal usage of this infrastructure is to treat a new ucode API
264 * release as a new hardware revision. That is, through utilizing the
265 * iwl_hcmd_utils_ops etc. we accommodate different command structures
266 * and flows between hardware versions (4965/5000) as well as their API
