205 * @fw_name_pre: Firmware filename prefix. The api version and extension
206 * (.ucode) will be added to filename before loading from disk. The
207 * filename is constructed as fw_name_pre<api>.ucode.
208 * @ucode_api_max: Highest version of uCode API supported by driver.
209 * @ucode_api_min: Lowest version of uCode API supported by driver.
210 * @max_ll_items: max number of OTP blocks
211 * @shadow_ram_support: shadow support for OTP memory
212 * @use_rts_for_ht: use rts/cts protection for HT traffic
213 *
214 * We enable the driver to be backward compatible wrt API version. The
215 * driver specifies which APIs it supports (with @ucode_api_max being the
216 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
217 * it has a supported API version. The firmware's API version will be
218 * stored in @iwl_priv, enabling the driver to make runtime changes based
219 * on firmware version used.
220 *
221 * For example,
222 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
223 * Driver interacts with Firmware API version >= 2.
224 * } else {
225 * Driver interacts with Firmware API version 1.
226 * }
227 *
228 * The ideal usage of this infrastructure is to treat a new ucode API
229 * release as a new hardware revision. That is, through utilizing the
230 * iwl_hcmd_utils_ops etc. we accommodate different command structures
231 * and flows between hardware versions (4965/5000) as well as their API
232 * versions.
