209 * struct iwl_cfg
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.
65b7998a 215 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 216 * @max_ll_items: max number of OTP blocks
217 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 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
47eef9bd 221 * @use_rts_for_ht: use rts/cts protection for HT traffic
d8c07e7a 222 * @chain_noise_num_beacons: number of beacons used to compute chain noise
a0987a8d
RC		 223 *
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.
230 *
231 * For example,
232 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
233 * Driver interacts with Firmware API version >= 2.
234 * } else {
235 * Driver interacts with Firmware API version 1.
236 * }
237 *
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
242 * versions.
