NAME

ieee80211_ctstoself_get - CTS-to-self frame generation function

SYNOPSIS

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);

ARGUMENTS

: 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.

DESCRIPTION

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.
