	 * For 11ac chipsets prior to AR900B version 2.0, a max of 512 bins are
	 * delivered.  However, there can be additional bins reported for
	 * AR900B version 2.0 and QCA9984 as described next:
	 *
	 * AR900B version 2.0: An additional tone is processed on the right
	 * hand side in order to facilitate detection of radar pulses out to
	 * the extreme band-edge of the channel frequency.
	 * Since the HW design processes four tones at a time,
	 * this requires one additional Dword to be added to the
	 * search FFT report.
	 *
	 * QCA9984: When spectral_scan_rpt_mode=2, i.e 2-dword summary +
	 * 1x-oversampled bins (in-band) per FFT,
	 * then 8 more bins (4 more on left side and 4 more on right side)
	 * are added.
