+ * @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.
