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