MEMBERS

       mactime
	   value in microseconds of the 64-bit Time Synchronization Function (TSF) timer when the first data symbol (MPDU) arrived at the
	   hardware.

       device_timestamp
	   arbitrary timestamp for the device, mac80211 doesn't use it but can store it and pass it back to the driver for synchronisation

       ampdu_reference
	   A-MPDU reference number, must be a different value for each A-MPDU but the same for each subframe within one A-MPDU

       flag
	   RX_FLAG_*

       vendor_radiotap_bitmap
	   radiotap vendor namespace presence bitmap

       vendor_radiotap_len
	   radiotap vendor namespace length

       freq
	   frequency the radio was tuned to when receiving this frame, in MHz

       rate_idx
	   index of data rate into band's supported rates or MCS index if HT or VHT is used (RX_FLAG_HT/RX_FLAG_VHT)

       vht_nss
	   number of streams (VHT only)

       rx_flags
	   internal RX flags for mac80211

       band
	   the active band when this frame was received

       antenna
	   antenna used

       signal
	   signal strength when receiving this frame, either in dBm, in dB or unspecified depending on the hardware capabilities flags
	   IEEE80211_HW_SIGNAL_*

       ampdu_delimiter_crc
	   A-MPDU delimiter CRC

       vendor_radiotap_align
	   radiotap vendor namespace alignment. Note that the actual data must be at the start of the SKB data already.

       vendor_radiotap_oui[3]
	   radiotap vendor namespace OUI

       vendor_radiotap_subns
	   radiotap vendor sub namespace

DESCRIPTION

       The low-level driver should provide this information (the subset supported by hardware) to the 802.11 code with each received frame, in the
       skb's control buffer (cb).
