The control socket code was written for AP+Client. It usually calls
STOP_AP before it attempts a new scan + assoc. When the interface is
connected again, it starts the AP again on the new operating frequency.
I don't think the problem is STOP_AP itself, I think the problem is the
lack of a start call when the mesh interface is set up properly.
