    ath9k_htc: Fix beaconing in IBSS mode · 9c6dda4e
    Sujith 提交于
    The current way of managing beaconing in ad-hoc
    mode has a subtle race - the beacon obtained from mac80211
    is freed in the SWBA handler rather than the TX
    completion routine. But transmission of beacons goes
    through the normal SKB queue maintained in hif_usb,
    leading to a situation where __skb_dequeue() in the TX
    completion handler goes kaput.
    
    Fix this by simply getting a beacon from mac80211 for
    every SWBA and free it in its completion routine.
