221 * @fw_name_pre: Firmware filename prefix. The api version and extension
222 * (.ucode) will be added to filename before loading from disk. The
223 * filename is constructed as fw_name_pre<api>.ucode.
224 * @ucode_api_max: Highest version of uCode API supported by driver.

226 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
227 * @max_ll_items: max number of OTP blocks
228 * @shadow_ram_support: shadow support for OTP memory
229 * @led_compensation: compensate on the led on/off time per HW according
230 * to the deviation to achieve the desired led frequency.
231 * The detail algorithm is described in iwl-led.c
232 * @use_rts_for_ht: use rts/cts protection for HT traffic
233 * @chain_noise_num_beacons: number of beacons used to compute chain noise
234 * @adv_thermal_throttle: support advance thermal throttle
235 * @support_ct_kill_exit: support ct kill exit condition

237 * @plcp_delta_threshold: plcp error rate threshold used to trigger
238 * radio tuning when there is a high receiving plcp error rate
240 * We enable the driver to be backward compatible wrt API version. The
241 * driver specifies which APIs it supports (with @ucode_api_max being the
242 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
243 * it has a supported API version. The firmware's API version will be
244 * stored in @iwl_priv, enabling the driver to make runtime changes based
245 * on firmware version used.
248 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
249 * Driver interacts with Firmware API version >= 2.
251 * Driver interacts with Firmware API version 1.
254 * The ideal usage of this infrastructure is to treat a new ucode API
255 * release as a new hardware revision. That is, through utilizing the
256 * iwl_hcmd_utils_ops etc. we accommodate different command structures
257 * and flows between hardware versions (4965/5000) as well as their API
