ieee80211_ctstoself_get - CTS-to-self frame generation function

void ieee80211_ctstoself_get(struct ieee80211_hw *  hw , struct ieee80211_vif *  vif , const void *  frame , size_t  frame_len , const struct ieee80211_tx_info *  frame_txctl , struct ieee80211_cts *  cts );

hw
    pointer obtained from ieee80211_alloc_hw.

vif
     struct ieee80211_vif pointer from the add_interface callback.

frame
    pointer to the frame that is going to be protected by the CTS-to-self.

frame_len
    the frame length (in octets).

frame_txctl
     struct ieee80211_tx_info of the frame.

cts
    The buffer where to store the CTS-to-self frame.

If the CTS-to-self frames are generated by the host system (i.e., not in hardware/firmware), the low-level driver uses this function to receive the next CTS-to-self frame from the 802.11 code. The low-level is responsible for calling this function before and CTS-to-self frame is needed.
