Also, we should check to see whether the MAC is paying attention to
any beacon frames and updating _its_ timestamp using that beacon frame
timer.
That's one of the mesh-and-sta-and-ap-at-the-same-time problems - in
STA mode, the TSF gets fudged based on the AP TSF. In other modes this
doesn't necessarily hold.
