167 * struct iwl_cfg
168 * @fw_name_pre: Firmware filename prefix. The api version and extension
169 * (.ucode) will be added to filename before loading from disk. The
170 * filename is constructed as fw_name_pre<api>.ucode.
171 * @ucode_api_max: Highest version of uCode API supported by driver.
172 * @ucode_api_min: Lowest version of uCode API supported by driver.
173 *
174 * We enable the driver to be backward compatible wrt API version. The
175 * driver specifies which APIs it supports (with @ucode_api_max being the
176 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
177 * it has a supported API version. The firmware's API version will be
178 * stored in @iwl_priv, enabling the driver to make runtime changes based
179 * on firmware version used.
180 *
181 * For example,
182 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
183 * Driver interacts with Firmware API version >= 2.
184 * } else {
185 * Driver interacts with Firmware API version 1.
186 * }
187 *
188 * The ideal usage of this infrastructure is to treat a new ucode API
189 * release as a new hardware revision. That is, through utilizing the
190 * iwl_hcmd_utils_ops etc. we accommodate different command structures
191 * and flows between hardware versions (4965/5000) as well as their API
192 * versions.
