242 * struct iwl_cfg
243 * @fw_name_pre: Firmware filename prefix. The api version and extension
244 * (.ucode) will be added to filename before loading from disk. The
245 * filename is constructed as fw_name_pre<api>.ucode.
246 * @ucode_api_max: Highest version of uCode API supported by driver.
247 * @ucode_api_min: Lowest version of uCode API supported by driver.
248 * @scan_antennas: available antenna for scan operation
249 * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
250 *
251 * We enable the driver to be backward compatible wrt API version. The
252 * driver specifies which APIs it supports (with @ucode_api_max being the
253 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
254 * it has a supported API version. The firmware's API version will be
255 * stored in @iwl_priv, enabling the driver to make runtime changes based
256 * on firmware version used.
257 *
258 * For example,
259 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
260 * Driver interacts with Firmware API version >= 2.
261 * } else {
262 * Driver interacts with Firmware API version 1.
263 * }
264 *
265 * The ideal usage of this infrastructure is to treat a new ucode API
266 * release as a new hardware revision. That is, through utilizing the
267 * iwl_hcmd_utils_ops etc. we accommodate different command structures
268 * and flows between hardware versions as well as their API
269 * versions.
