struct ieee80211_rx_status — receive status

Synopsis

struct ieee80211_rx_status {
  u64 mactime;
  enum ieee80211_band band;
  int freq;
  int signal;
  int noise;
  int qual;
  int antenna;

};

Members

mactime: value in microseconds of the 64-bit Time Synchronization Function (TSF) timer when the first data symbol (MPDU) arrived at the hardware.
band: the active band when this frame was received
freq: frequency the radio was tuned to when receiving this frame, in MHz
signal: signal strength when receiving this frame, either in dBm, in dB or unspecified depending on the hardware capabilities flags IEEE80211_HW_SIGNAL_*
noise: noise when receiving this frame, in dBm.
qual: overall signal quality indication, in percent (0-100).
antenna: antenna used
rate_idx: index of data rate into band's supported rates or MCS index if HT rates are use (RX_FLAG_HT)
flag: RX_FLAG_*

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).
