 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.
