 267  * highest and @ucode_api_min the lowest). Firmware will only be loaded if
 268  * it has a supported API version. The firmware's API version will be
 269  * stored in @iwl_priv, enabling the driver to make runtime changes based
 270  * on firmware version used.
 271  *
 272  * For example,
 273  * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
 274  *      Driver interacts with Firmware API version >= 2.
 275  * } else {

 277  * }
 278  *
 279  * The ideal usage of this infrastructure is to treat a new ucode API
 280  * release as a new hardware revision. That is, through utilizing the
 281  * iwl_hcmd_utils_ops etc. we accommodate different command structures
 282  * and flows between hardware versions (4965/5000) as well as their API
 283  * versions.
