176 * struct iwl_cfg
177 * @fw_name_pre: Firmware filename prefix. The api version and extension
178 * (.ucode) will be added to filename before loading from disk. The
179 * filename is constructed as fw_name_pre<api>.ucode.
180 * @ucode_api_max: Highest version of uCode API supported by driver.
181 * @ucode_api_min: Lowest version of uCode API supported by driver.
182 *
183 * We enable the driver to be backward compatible wrt API version. The
184 * driver specifies which APIs it supports (with @ucode_api_max being the
185 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
186 * it has a supported API version. The firmware's API version will be
187 * stored in @iwl_priv, enabling the driver to make runtime changes based
188 * on firmware version used.
189 *
190 * For example,
191 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
192 * Driver interacts with Firmware API version >= 2.
193 * } else {
194 * Driver interacts with Firmware API version 1.
195 * }
196 *
197 * The ideal usage of this infrastructure is to treat a new ucode API
198 * release as a new hardware revision. That is, through utilizing the
199 * iwl_hcmd_utils_ops etc. we accommodate different command structures
200 * and flows between hardware versions (4965/5000) as well as their API
201 * versions.
