ath9k_htc: Fix module unloading issue
The maximum number of packets in a single buffer in stream mode is 10. The driver currently uses 8 - which caused stack corruption, in the absence of any kind of OOB checking. Fixing this to the correct value of 10 fixes the module unload issue. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Tested-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: John W.
