This patch enables mesh point operation for ath9k. Tested with b43
and ath5k as peers.

Currently, you need to trigger a scan on the mesh point interface to
enable beaconing. This is the same behavior the ath5k, rt2500usb and
rt61pci drivers exhibit. Is this a mac80211 design flaw, or something
in all of these drivers?
