Get the duration field for a cts-to-self frame
__le16 ieee80211_ctstoself_duration(struct ieee80211_hw * hw, struct ieee80211_vif * vif, size_t frame_len, const struct ieee80211_tx_info * frame_txctl);
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.
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.
The duration.
