 * @ch_width:                 Channel width 20/40/80/160 MHz
 * @spectral_mode:            Spectral scan mode
 * @spectral_pri80ind:        Indication from hardware that the sample was
 *                            received on the primary 80 MHz segment. If this
 *                            is set when smode = SPECTRAL_SCAN_MODE_AGILE, it
 *                            indicates that Spectral was carried out on pri80
 *                            instead of the Agile frequency due to a
 *                            channel switch - Software may choose
 *                            to ignore the sample in this case.
 * @spectral_pri80ind_sec80:  Indication from hardware that the sample was
 *                            received on the primary 80 MHz segment instead of
 *                            the secondary 80 MHz segment due to a channel
 *                            switch - Software may choose to ignore the sample
 *                            if this is set. Applicable only if smode =
 *                            SPECTRAL_SCAN_MODE_NORMAL and for 160/80+80 MHz
 *                            Spectral operation.
 * @last_raw_timestamp:       Previous FFT report's raw timestamp. In case of
 *                            160Mhz it will be primary 80 segment's timestamp
 *                            as both primary & secondary segment's timestamp
 *                            are expected to be almost equal.
 * @timestamp_war_offset:     Offset calculated based on reset_delay and
 *                            last_raw_timestamp. It will be added to
 *                            raw_timestamp to get spectral_tstamp.
 * @raw_timestamp:            Actual FFT timestamp reported by HW on primary
 *                            segment.
 * @raw_timestamp_sec80:      Actual FFT timestamp reported by HW on sec80 MHz
 *                            segment.
 * @reset_delay:              Time gap between the last spectral report before
 *                            reset and the end of reset. It is provided by FW
 *                            via direct DMA framework.
 * @target_reset_count:       Indicates the number of times target went through
 *                            reset routine after spectral was enabled.
 * @bin_pwr_count_5mhz:       Indicates the number of FFT bins in the extra
 *                            5 MHz for 165 MHz/ Restricted 80p80 mode
 * @bin_pwr_5mhz:             Contains FFT magnitudes corresponding to the extra
 *                            5 MHz in 165 MHz/ Restricted 80p80 mode
