202/**
203 * struct iwl_cfg
204 * @fw_name_pre: Firmware filename prefix. The api version and extension
205 * (.ucode) will be added to filename before loading from disk. The
206 * filename is constructed as fw_name_pre<api>.ucode.
207 * @ucode_api_max: Highest version of uCode API supported by driver.
208 * @ucode_api_min: Lowest version of uCode API supported by driver.
209 *
210 * We enable the driver to be backward compatible wrt API version. The
211 * driver specifies which APIs it supports (with @ucode_api_max being the
212 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
213 * it has a supported API version. The firmware's API version will be
214 * stored in @iwl_priv, enabling the driver to make runtime changes based
215 * on firmware version used.
216 *
217 * For example,
218 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
219 * Driver interacts with Firmware API version >= 2.
220 * } else {
221 * Driver interacts with Firmware API version 1.
222 * }
223 *
224 * The ideal usage of this infrastructure is to treat a new ucode API
225 * release as a new hardware revision. That is, through utilizing the
226 * iwl_hcmd_utils_ops etc. we accommodate different command structures
227 * and flows between hardware versions (4965/5000) as well as their API
228 * versions.
