232 | * @fw_name_pre: Firmware filename prefix. The api version and extension | |
233 | * (.ucode) will be added to filename before loading from disk. The | |
234 | * filename is constructed as fw_name_pre<api>.ucode. | |
235 | * @ucode_api_max: Highest version of uCode API supported by driver. | |
236 | * @ucode_api_min: Lowest version of uCode API supported by driver. | |
65b7998a | 237 | * @pa_type: used by 6000 series only to identify the type of Power Amplifier |
415e4993 WYG |
238 | * @max_ll_items: max number of OTP blocks |
239 | * @shadow_ram_support: shadow support for OTP memory | |
f2d0d0e2 WYG |
240 | * @led_compensation: compensate on the led on/off time per HW according |
241 | * to the deviation to achieve the desired led frequency. | |
242 | * The detail algorithm is described in iwl-led.c | |
47eef9bd | 243 | * @use_rts_for_ht: use rts/cts protection for HT traffic |
d8c07e7a | 244 | * @chain_noise_num_beacons: number of beacons used to compute chain noise |
6047b4f9 | 245 | * @adv_thermal_throttle: support advance thermal throttle |
480e8407 | 246 | * @support_ct_kill_exit: support ct kill exit condition |
1933ac4d | 247 | * @support_wimax_coexist: support wimax/wifi co-exist |
3e4fb5fa TAN |
248 | * @plcp_delta_threshold: plcp error rate threshold used to trigger |
249 | * radio tuning when there is a high receiving plcp error rate | |
a0987a8d RC |
250 | * |
251 | * We enable the driver to be backward compatible wrt API version. The | |
252 | * driver specifies which APIs it supports (with @ucode_api_max being the | |
253 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if | |
254 | * it has a supported API version. The firmware's API version will be | |
255 | * stored in @iwl_priv, enabling the driver to make runtime changes based | |
256 | * on firmware version used. | |
257 | * | |
258 | * For example, | |
259 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { | |
260 | * Driver interacts with Firmware API version >= 2. | |
261 | * } else { | |
262 | * Driver interacts with Firmware API version 1. | |
263 | * } | |
264 | * | |
265 | * The ideal usage of this infrastructure is to treat a new ucode API | |
266 | * release as a new hardware revision. That is, through utilizing the | |
267 | * iwl_hcmd_utils_ops etc. we accommodate different command structures | |
268 | * and flows between hardware versions (4965/5000) as well as their API | |
269 | * versions. | |
