210 * @fw_name_pre: Firmware filename prefix. The api version and extension
211 * (.ucode) will be added to filename before loading from disk. The
212 * filename is constructed as fw_name_pre<api>.ucode.
213 * @ucode_api_max: Highest version of uCode API supported by driver.
214 * @ucode_api_min: Lowest version of uCode API supported by driver.
215 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
216 * @max_ll_items: max number of OTP blocks
217 * @shadow_ram_support: shadow support for OTP memory
218 * @led_compensation: compensate on the led on/off time per HW according
219 * to the deviation to achieve the desired led frequency.
220 * The detail algorithm is described in iwl-led.c
221 * @use_rts_for_ht: use rts/cts protection for HT traffic
222 * @chain_noise_num_beacons: number of beacons used to compute chain noise
224 * We enable the driver to be backward compatible wrt API version. The
225 * driver specifies which APIs it supports (with @ucode_api_max being the
226 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
227 * it has a supported API version. The firmware's API version will be
228 * stored in @iwl_priv, enabling the driver to make runtime changes based
229 * on firmware version used.
232 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
233 * Driver interacts with Firmware API version >= 2.
235 * Driver interacts with Firmware API version 1.
238 * The ideal usage of this infrastructure is to treat a new ucode API
239 * release as a new hardware revision. That is, through utilizing the
240 * iwl_hcmd_utils_ops etc. we accommodate different command structures
241 * and flows between hardware versions (4965/5000) as well as their API
