NAME

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;
   int rate_idx;
   int flag;
 };

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.
