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.
