3. 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 doesnAqt 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 bandAqs 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

4. 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 skbAqs control buffer (cb).
