 225  * it has a supported API version. The firmware's API version will be
 226  * stored in @iwl_priv, enabling the driver to make runtime changes based
 227  * on firmware version used.

 229  * For example,
 230  * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
 231  *      Driver interacts with Firmware API version >= 2.
 232  * } else {
