 177  * @fw_name_pre: Firmware filename prefix. The api version and extension
 178  *      (.ucode) will be added to filename before loading from disk. The
 179  *      filename is constructed as fw_name_pre<api>.ucode.
 180  * @ucode_api_max: Highest version of uCode API supported by driver.
 181  * @ucode_api_min: Lowest version of uCode API supported by driver.
 182  *
 183  * We enable the driver to be backward compatible wrt API version. The
 184  * driver specifies which APIs it supports (with @ucode_api_max being the
 185  * highest and @ucode_api_min the lowest). Firmware will only be loaded if
 186  * it has a supported API version. The firmware's API version will be
 187  * stored in @iwl_priv, enabling the driver to make runtime changes based
 188  * on firmware version used.
 189  *
 190  * For example,
 191  * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
 192  *      Driver interacts with Firmware API version >= 2.
 193  * } else {
 194  *      Driver interacts with Firmware API version 1.
 195  * }
 196  *
 197  * The ideal usage of this infrastructure is to treat a new ucode API
 198  * release as a new hardware revision. That is, through utilizing the
 199  * iwl_hcmd_utils_ops etc. we accommodate different command structures
 200  * and flows between hardware versions (4965/5000) as well as their API
 201  * versions.
