ieee80211_rts_duration - Get the duration field for an RTS frame

2. SYNOPSIS

__le16 ieee80211_rts_duration(struct ieee80211_hw *  hw , struct ieee80211_vif *  vif , size_t  frame_len , const struct ieee80211_tx_info *  frame_txctl );

3. 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 RTS.

frame_txctl
     struct ieee80211_tx_info of the frame.
