 262  * We enable the driver to be backward compatible wrt API version. The

 264  * highest and @ucode_api_min the lowest). Firmware will only be loaded if
 265  * it has a supported API version. The firmware's API version will be
 266  * stored in @iwl_priv, enabling the driver to make runtime changes based
 267  * on firmware version used.
 268  *
 269  * For example,
 270  * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
 271  *      Driver interacts with Firmware API version >= 2.
 272  * } else {
 273  *      Driver interacts with Firmware API version 1.
 274  * }
 275  *
 276  * The ideal usage of this infrastructure is to treat a new ucode API
 277  * release as a new hardware revision. That is, through utilizing the
 278  * iwl_hcmd_utils_ops etc. we accommodate different command structures
 279  * and flows between hardware versions (4965/5000) as well as their API
 280  * versions.
