264 * We enable the driver to be backward compatible wrt API version. The
265 * driver specifies which APIs it supports (with @ucode_api_max being the
266 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
267 * it has a supported API version. The firmware's API version will be
268 * stored in @iwl_priv, enabling the driver to make runtime changes based
269 * on firmware version used.
270 *
271 * For example,
272 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
7cb1b088 273 * Driver interacts with Firmware API version >= 2.

RC		 276 * }
277 *
278 * The ideal usage of this infrastructure is to treat a new ucode API
279 * release as a new hardware revision. That is, through utilizing the
280 * iwl_hcmd_utils_ops etc. we accommodate different command structures
281 * and flows between hardware versions (4965/5000) as well as their API
282 * versions.
