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

flag

RX_FLAG_*

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 rates are use (RX_FLAG_HT)

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_*

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).
