value in microseconds of the 64-bit Time Synchronization Function (TSF) timer when the first data symbol (MPDU) arrived at the hardware.
arbitrary timestamp for the device, mac80211 doesn't use it but can store it and pass it back to the driver for synchronisation
A-MPDU reference number, must be a different value for each A-MPDU but the same for each subframe within one A-MPDU
RX_FLAG_
*
radiotap vendor namespace presence bitmap
radiotap vendor namespace length
frequency the radio was tuned to when receiving this frame, in MHz
index of data rate into band's supported rates or MCS index if
HT or VHT is used (RX_FLAG_HT
/RX_FLAG_VHT
)
number of streams (VHT only)
internal RX flags for mac80211
the active band when this frame was received
antenna used
signal strength when receiving this frame, either in dBm, in dB or
unspecified depending on the hardware capabilities flags
IEEE80211_HW_SIGNAL_
*
A-MPDU delimiter CRC
radiotap vendor namespace alignment. Note that the actual data must be at the start of the SKB data already.
radiotap vendor namespace OUI
radiotap vendor sub namespace
