244 * @ucode_api_min: Lowest version of uCode API supported by driver.

256 * We enable the driver to be backward compatible wrt API version. The
257 * driver specifies which APIs it supports (with @ucode_api_max being 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) {
7cb1b088 265 * Driver interacts with Firmware API version >= 2.
a0987a8d 266 * } else {
7cb1b088 267 * Driver interacts with Firmware API version 1.
a0987a8d
RC		 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.
