215 * @fw_name_pre: Firmware filename prefix. The api version and extension

222 * @shadow_ram_support: shadow support for OTP memory
223 * @led_compensation: compensate on the led on/off time per HW according
224 * to the deviation to achieve the desired led frequency.
225 * The detail algorithm is described in iwl-led.c

229 * We enable the driver to be backward compatible wrt API version. The
230 * driver specifies which APIs it supports (with @ucode_api_max being the
231 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
232 * it has a supported API version. The firmware's API version will be
233 * stored in @iwl_priv, enabling the driver to make runtime changes based
234 * on firmware version used.

238 * Driver interacts with Firmware API version >= 2.
240 * Driver interacts with Firmware API version 1.
243 * The ideal usage of this infrastructure is to treat a new ucode API
244 * release as a new hardware revision. That is, through utilizing the
245 * iwl_hcmd_utils_ops etc. we accommodate different command structures
246 * and flows between hardware versions (4965/5000) as well as their API
