Description (partial)

Symptom:
%DOT11-6-DFS_TRIGGERED: DFS: triggered on frequency 5320 MHz
%LINK-6-UPDOWN: Interface Dot11Radio1, changed state to down
%LINK-5-CHANGED: Interface Dot11Radio1, changed state to reset
%LINEPROTO-5-UPDOWN: Line protocol on Interface Dot11Radio1, changed state to down
%DOT11-2-CHAN_NOT_AVAIL: Interface Dot11Radio1, DFS: Configured frequency (5280 MHz) unavailable for 30 minute(s).

Conditions:
It is Expected behaviour to disable Transmit on current channel for 30 mins, when the radar detected on the current channel also there is no available non-dfs channel on the DCA list.
But the radio reset due to beacon stuck in this scenario should be avoided.
