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