217 * struct iwl_cfg
218 * @fw_name_pre: Firmware filename prefix. The api version and extension
219 * (.ucode) will be added to filename before loading from disk. The
220 * filename is constructed as fw_name_pre<api>.ucode.
221 * @ucode_api_max: Highest version of uCode API supported by driver.
222 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 223 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 224 * @max_ll_items: max number of OTP blocks
225 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 226 * @led_compensation: compensate on the led on/off time per HW according
227 * to the deviation to achieve the desired led frequency.
228 * The detail algorithm is described in iwl-led.c
47eef9bd 229 * @use_rts_for_ht: use rts/cts protection for HT traffic
d8c07e7a 230 * @chain_noise_num_beacons: number of beacons used to compute chain noise
6047b4f9 231 * @adv_thermal_throttle: support advance thermal throttle
480e8407 232 * @support_ct_kill_exit: support ct kill exit condition
c15d20c1 233 * @sm_ps_mode: spatial multiplexing power save mode
1933ac4d 234 * @support_wimax_coexist: support wimax/wifi co-exist
a0987a8d
RC		 235 *
236 * We enable the driver to be backward compatible wrt API version. The
237 * driver specifies which APIs it supports (with @ucode_api_max being the
238 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
239 * it has a supported API version. The firmware's API version will be
240 * stored in @iwl_priv, enabling the driver to make runtime changes based
241 * on firmware version used.
242 *
243 * For example,
244 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
245 * Driver interacts with Firmware API version >= 2.
246 * } else {
247 * Driver interacts with Firmware API version 1.
248 * }
249 *
250 * The ideal usage of this infrastructure is to treat a new ucode API
251 * release as a new hardware revision. That is, through utilizing the
252 * iwl_hcmd_utils_ops etc. we accommodate different command structures
253 * and flows between hardware versions (4965/5000) as well as their API
254 * versions.
