192 * struct iwl_cfg
193 * @fw_name_pre: Firmware filename prefix. The api version and extension
194 * (.ucode) will be added to filename before loading from disk. The
195 * filename is constructed as fw_name_pre<api>.ucode.
196 * @ucode_api_max: Highest version of uCode API supported by driver.
197 * @ucode_api_min: Lowest version of uCode API supported by driver.
198 *
199 * We enable the driver to be backward compatible wrt API version. The
200 * driver specifies which APIs it supports (with @ucode_api_max being the
201 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
202 * it has a supported API version. The firmware's API version will be
203 * stored in @iwl_priv, enabling the driver to make runtime changes based
204 * on firmware version used.
205 *
206 * For example,
207 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
208 * Driver interacts with Firmware API version >= 2.
209 * } else {
210 * Driver interacts with Firmware API version 1.
211 * }
212 *
213 * The ideal usage of this infrastructure is to treat a new ucode API
214 * release as a new hardware revision. That is, through utilizing the
215 * iwl_hcmd_utils_ops etc. we accommodate different command structures
216 * and flows between hardware versions (4965/5000) as well as their API
217 * versions.
