    ath9k: Restart xmit logic in xmit watchdog. · 60f2d1d5
    Ben Greear authored
    The system can get into a state where the xmit queue
    is stopped, but there are no packets pending, so
    the queue will not be restarted.
    
    Add logic to the xmit watchdog to attempt to restart
    the xmit logic if this situation is detected.
    
    Example 'dmesg' output:
    
    ath: txq: f4e723e0 axq_qnum: 2, mac80211_qnum: 2 axq_link: f4e996c8 pending frames: 1 axq_acq empty: 1 stopped: 0 axq_depth: 0  Attempting to restart tx logic.
