ieee80211_rts_duration(9) 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.
