-    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.

-    ath9k_hw: fix PLL clock initialization for newer SoC
-    
-    On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
-    register changed. This currently breaks at least 5/10 MHz operation.
-    AR933x uses the old layout.
-    
-    It might also have been causing other stability issues because of the
-    different location of the PLL_BYPASS bit which needs to be set during
-    PLL clock initialization.
-    
-    This patch also removes more instances of hardcoded register values in
-    favor of properly computed ones with the PLL_BYPASS bit added.

-    On AR934x rev 3, settin the ad-hoc flag completely messes up hardware
