IEEE80211_RTS_DURATI(9)           The basic mac80211 driver inte          IEEE80211_RTS_DURATI(9)



NAME
       ieee80211_rts_duration - Get the duration field for an RTS frame

SYNOPSIS
       __le16 ieee80211_rts_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 RTS.

       frame_txctl
           struct ieee80211_tx_info of the frame.

DESCRIPTION
       If the RTS 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.
