214 * struct iwl_cfg
215 * @fw_name_pre: Firmware filename prefix. The api version and extension
216 * (.ucode) will be added to filename before loading from disk. The
217 * filename is constructed as fw_name_pre<api>.ucode.
218 * @ucode_api_max: Highest version of uCode API supported by driver.
219 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 220 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 221 * @max_ll_items: max number of OTP blocks
222 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 223 * @led_compensation: compensate on the led on/off time per HW according
224 * to the deviation to achieve the desired led frequency.
225 * The detail algorithm is described in iwl-led.c
47eef9bd 226 * @use_rts_for_ht: use rts/cts protection for HT traffic
d8c07e7a 227 * @chain_noise_num_beacons: number of beacons used to compute chain noise
a0987a8d
RC		 228 *
229 * We enable the driver to be backward compatible wrt API version. The
230 * driver specifies which APIs it supports (with @ucode_api_max being the
231 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
232 * it has a supported API version. The firmware's API version will be
233 * stored in @iwl_priv, enabling the driver to make runtime changes based
234 * on firmware version used.
235 *
236 * For example,
237 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
238 * Driver interacts with Firmware API version >= 2.
239 * } else {
240 * Driver interacts with Firmware API version 1.
241 * }
242 *
243 * The ideal usage of this infrastructure is to treat a new ucode API
244 * release as a new hardware revision. That is, through utilizing the
245 * iwl_hcmd_utils_ops etc. we accommodate different command structures
246 * and flows between hardware versions (4965/5000) as well as their API
247 * versions.
