207 * struct iwl_cfg
208 * @fw_name_pre: Firmware filename prefix. The api version and extension
209 * (.ucode) will be added to filename before loading from disk. The
210 * filename is constructed as fw_name_pre<api>.ucode.
211 * @ucode_api_max: Highest version of uCode API supported by driver.
212 * @ucode_api_min: Lowest version of uCode API supported by driver.
65b7998a 213 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
415e4993
WYG		 214 * @max_ll_items: max number of OTP blocks
215 * @shadow_ram_support: shadow support for OTP memory
f2d0d0e2
WYG		 216 * @led_compensation: compensate on the led on/off time per HW according
217 * to the deviation to achieve the desired led frequency.
218 * The detail algorithm is described in iwl-led.c
47eef9bd 219 * @use_rts_for_ht: use rts/cts protection for HT traffic
a0987a8d
RC		 220 *
221 * We enable the driver to be backward compatible wrt API version. The
222 * driver specifies which APIs it supports (with @ucode_api_max being the
223 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
224 * it has a supported API version. The firmware's API version will be
225 * stored in @iwl_priv, enabling the driver to make runtime changes based
226 * on firmware version used.
227 *
228 * For example,
229 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
230 * Driver interacts with Firmware API version >= 2.
231 * } else {
232 * Driver interacts with Firmware API version 1.
233 * }
234 *
235 * The ideal usage of this infrastructure is to treat a new ucode API
236 * release as a new hardware revision. That is, through utilizing the
237 * iwl_hcmd_utils_ops etc. we accommodate different command structures
238 * and flows between hardware versions (4965/5000) as well as their API
239 * versions.
