FreeBSD has off-line scanning only.  If you scan while associated, it
get just one.  No clue how they find the others on other channels
under windows.  Prism2 firmware, as documented, doesn't seem to
support this.  I should note that in hostap mode that you see all
beacons for all channels.  I've not looked into why this might be
(since in debug mode on FreeBSD you see every beacon, even for those
APs that aren't on the same channel).  Maybe windows just puts the
card into promiscuous (or hostap) mode for a bit and then waits a few
hundreds of milliseconds for all the beacons to come in.
