241 * struct iwl_cfg
242 * @fw_name_pre: Firmware filename prefix. The api version and extension
243 * (.ucode) will be added to filename before loading from disk. The
244 * filename is constructed as fw_name_pre<api>.ucode.
245 * @ucode_api_max: Highest version of uCode API supported by driver.
246 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 247 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 248 * @max_ll_items: max number of OTP blocks
249 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 250 * @led_compensation: compensate on the led on/off time per HW according
251 * to the deviation to achieve the desired led frequency.
252 * The detail algorithm is described in iwl-led.c
47eef9bd 253 * @use_rts_for_ht: use rts/cts protection for HT traffic
d8c07e7a 254 * @chain_noise_num_beacons: number of beacons used to compute chain noise
6047b4f9 255 * @adv_thermal_throttle: support advance thermal throttle
480e8407 256 * @support_ct_kill_exit: support ct kill exit condition
1933ac4d 257 * @support_wimax_coexist: support wimax/wifi co-exist
3e4fb5fa
TAN		 258 * @plcp_delta_threshold: plcp error rate threshold used to trigger
259 * radio tuning when there is a high receiving plcp error rate
a0987a8d
RC		 260 *
261 * We enable the driver to be backward compatible wrt API version. The
262 * driver specifies which APIs it supports (with @ucode_api_max being the
263 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
264 * it has a supported API version. The firmware's API version will be
265 * stored in @iwl_priv, enabling the driver to make runtime changes based
266 * on firmware version used.
267 *
268 * For example,
269 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
270 * Driver interacts with Firmware API version >= 2.
271 * } else {
272 * Driver interacts with Firmware API version 1.
273 * }
274 *
275 * The ideal usage of this infrastructure is to treat a new ucode API
276 * release as a new hardware revision. That is, through utilizing the
277 * iwl_hcmd_utils_ops etc. we accommodate different command structures
278 * and flows between hardware versions (4965/5000) as well as their API
279 * versions.
