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.

RETURN
       The duration.
