 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.

 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.
