++    ath9k: fix aggregation session lockup
++    
++    If an aggregation session fails, frames still end up in the driver queue
++    with IEEE80211_TX_CTL_AMPDU set.
++    This causes tx for the affected station/tid to stall, since
++    ath_tx_get_tid_subframe returning packets to send.
++    
++    Fix this by clearing IEEE80211_TX_CTL_AMPDU as long as no aggregation
++    session is running.
