IEEE80211_RX(9) 					  The basic mac80211 driver inte					   IEEE80211_RX(9)

NAME

       ieee80211_rx - receive frame

SYNOPSIS

       void ieee80211_rx(struct ieee80211_hw * hw, struct sk_buff * skb);

ARGUMENTS

       hw
	   the hardware this frame came in on

       skb
	   the buffer to receive, owned by mac80211 after this call

DESCRIPTION

       Use this function to hand received frames to mac80211. The receive buffer in skb must start with an IEEE 802.11 header.

       This function may not be called in IRQ context. Calls to this function for a single hardware must be synchronized against each other. Calls
       to this function, ieee80211_rx_ni and ieee80211_rx_irqsafe may not be mixed for a single hardware.

       In process context use instead ieee80211_rx_ni.

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 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.

       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).
