   * @fw_name_pre: Firmware filename prefix. The api version and extension

   * @ucode_api_max: Highest version of uCode API supported by driver.
   * @ucode_api_min: Lowest version of uCode API supported by driver.
   * @pa_type: used by 6000 series only to identify the type of Power Amplifier

   * @need_temp_offset_calib: need to perform temperature offset calibration
   * @scan_antennas: available antenna for scan operation

   * We enable the driver to be backward compatible wrt API version. The
   * driver specifies which APIs it supports (with @ucode_api_max being the
   * highest and @ucode_api_min the lowest). Firmware will only be loaded if
   * it has a supported API version. The firmware's API version will be
   * stored in @iwl_priv, enabling the driver to make runtime changes based
   * on firmware version used.
   *
   * For example,
   * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
   *	Driver interacts with Firmware API version >= 2.
   * } else {
   *	Driver interacts with Firmware API version 1.
   * }
   *
   * The ideal usage of this infrastructure is to treat a new ucode API
   * release as a new hardware revision. That is, through utilizing the
   * iwl_hcmd_utils_ops etc. we accommodate different command structures
   * and flows between hardware versions (4965/5000) as well as their API
   * versions.
