The beaconing API in total is a bit strange, we tell the driver when the
beacon changes and it can then request one, but we never tell it when to
start/stop beaconing, which means that currently your driver has to
figure to start out beaconing on the first beacon change, and then
cannot possibly stop again... We can return NULL from the beacon get
function but that could be an error condition too...

The original design was for AP mode only and the assumption was that
Beacon transmission is enabled pretty much all the time. Returning NULL
was used if ever needed to stop Beacon transmission for some period of
time.

I think we just need to add start/stop beacon bits, and then we can use
them around a scan too, thoughts?

That sounds reasonable.
