IEEE80211_CTSTOSELF_(9) 				  The basic mac80211 driver inte				   IEEE80211_CTSTOSELF_(9)

NAME

       ieee80211_ctstoself_duration - Get the duration field for a CTS-to-self frame

SYNOPSIS

       __le16 ieee80211_ctstoself_duration(struct ieee80211_hw * hw, struct ieee80211_vif * vif, size_t frame_len,
					   const struct ieee80211_tx_info * frame_txctl);

ARGUMENTS

       hw
	   pointer obtained from ieee80211_alloc_hw.

       vif

	   struct ieee80211_vif pointer from the add_interface callback.

       frame_len
	   the length of the frame that is going to be protected by the CTS-to-self.

       frame_txctl

	   struct ieee80211_tx_info of the frame.

DESCRIPTION

       If the CTS-to-self is generated in firmware, but the host system must provide the duration field, the low-level driver uses this function
       to receive the duration field value in little-endian byteorder.

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).
