[PATCH] mac80211: ignore tx status for PS stations in ieee80211_tx_status_ext

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Make it behave like regular ieee80211_tx_status calls, except for the lack of
filtered frame processing.
This fixes spurious low-ack triggered disconnections with powersave clients
connected to an AP.
