+ ath9k: Fix crash in MCC mode
+
+ When a channel context is removed, the hw_queue_base
+ is set to -1, this will result in a panic because
+ ath9k_chanctx_stop_queues() can be called on an interface
+ that is not assigned to any context yet - for example,
+ when trying to scan.
+
+ Fix this issue by setting the hw_queue_base to zero
+ when a channel context is removed.

+
+ ath9k: Fix flushing in MCC mode
+
+ When we are attempting to switch to a new
+ channel context, the TX queues are flushed, but
+ the mac80211 queues are not stopped and traffic
+ can still come down to the driver.
+
+ This patch fixes it by stopping the queues
+ assigned to the current context/vif before
+ trying to flush.

+
+ ath9k: Fix queue handling for channel contexts
+
+ When a full chip reset is done, all the queues
+ across all VIFs are stopped, but if MCC is enabled,
+ only the queues of the current context is awakened,
+ when we complete the reset.
+
+ This results in unfairness for the inactive context.
+ Since frames are queued internally in the driver if
+ there is a context mismatch, we can awaken all the
+ queues when coming out of a reset.
+
+ The VIF-specific queues are still used in flow control,
+ to ensure fairness when traffic is high.
