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

 258  * highest and @ucode_api_min the lowest). Firmware will only be loaded if
 259  * it has a supported API version. The firmware's API version will be
 260  * stored in @iwl_priv, enabling the driver to make runtime changes based
 261  * on firmware version used.
 262  *
 263  * For example,
 264  * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
 265  *      Driver interacts with Firmware API version >= 2.
 266  * } else {
 267  *      Driver interacts with Firmware API version 1.
 268  * }
 269  *
 270  * The ideal usage of this infrastructure is to treat a new ucode API
 271  * release as a new hardware revision. That is, through utilizing the
 272  * iwl_hcmd_utils_ops etc. we accommodate different command structures
 273  * and flows between hardware versions (4965/5000) as well as their API
 274  * versions.
