| IEEE80211_CTSTOSELF_(9) | The basic mac80211 driver inte | IEEE80211_CTSTOSELF_(9) |
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.
