Description (partial)

%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).

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.
