ath9k_htc: Add a timer to cleanup WMI events
Occasionally, a WMI event would arrive ahead of the TX URB completion handler. Discarding these events would exhaust the available TX slots, so handle them by running a timer cleaning up such events. Also, timeout packets for which TX completion events have not arrived. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
