215 * struct iwl_cfg
216 * @fw_name_pre: Firmware filename prefix. The api version and extension
217 * (.ucode) will be added to filename before loading from disk. The
218 * filename is constructed as fw_name_pre<api>.ucode.
219 * @ucode_api_max: Highest version of uCode API supported by driver.
220 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 221 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 222 * @max_ll_items: max number of OTP blocks
223 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 224 * @led_compensation: compensate on the led on/off time per HW according
225 * to the deviation to achieve the desired led frequency.
226 * The detail algorithm is described in iwl-led.c
47eef9bd 227 * @use_rts_for_ht: use rts/cts protection for HT traffic
d8c07e7a 228 * @chain_noise_num_beacons: number of beacons used to compute chain noise
6047b4f9 229 * @adv_thermal_throttle: support advance thermal throttle
480e8407 230 * @support_ct_kill_exit: support ct kill exit condition
c15d20c1 231 * @sm_ps_mode: spatial multiplexing power save mode

a0987a8d
RC		 233 *
234 * We enable the driver to be backward compatible wrt API version. The
235 * driver specifies which APIs it supports (with @ucode_api_max being the
236 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
237 * it has a supported API version. The firmware's API version will be
238 * stored in @iwl_priv, enabling the driver to make runtime changes based
239 * on firmware version used.
240 *
241 * For example,
242 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
243 * Driver interacts with Firmware API version >= 2.
244 * } else {
245 * Driver interacts with Firmware API version 1.
246 * }
247 *
248 * The ideal usage of this infrastructure is to treat a new ucode API
249 * release as a new hardware revision. That is, through utilizing the
250 * iwl_hcmd_utils_ops etc. we accommodate different command structures
251 * and flows between hardware versions (4965/5000) as well as their API
252 * versions.
