233 * struct iwl_cfg
234 * @fw_name_pre: Firmware filename prefix. The api version and extension
235 * (.ucode) will be added to filename before loading from disk. The
236 * filename is constructed as fw_name_pre<api>.ucode.
237 * @ucode_api_max: Highest version of uCode API supported by driver.
238 * @ucode_api_min: Lowest version of uCode API supported by driver.
239 * @scan_antennas: available antenna for scan operation
240 * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
241 *
242 * We enable the driver to be backward compatible wrt API version. The
243 * driver specifies which APIs it supports (with @ucode_api_max being the
244 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
245 * it has a supported API version. The firmware's API version will be
246 * stored in @iwl_priv, enabling the driver to make runtime changes based
247 * on firmware version used.
248 *
249 * For example,
250 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
251 * Driver interacts with Firmware API version >= 2.
252 * } else {
253 * Driver interacts with Firmware API version 1.
254 * }
255 *
256 * The ideal usage of this infrastructure is to treat a new ucode API
257 * release as a new hardware revision. That is, through utilizing the
258 * iwl_hcmd_utils_ops etc. we accommodate different command structures
259 * and flows between hardware versions as well as their API
260 * versions.
