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