Hi,
In the Regulatory and DFS wiki it is mentioned that
beacon hints are not processed for DFS channels.
But i could not find the related piece of code which
does this.
So in DFS channels can we process beacon hints?
Assuming that if AP is beaconing then there is no
RADAR in that channel. But how do we handle
channel switch (if we dont disconnect) then that
channel is enabled for active scan?
(or)
should be we have something like this:
