Upon further investigation, beaconing does not work after configuring
an interface in mesh point mode but running 'iwlist mesh scan'
triggers something in the driver that enables beaconing.
After executing this command beacons are generated and correctly
received at other nodes.

This behaviour is present using both rt73usb and rt2500pci based cards.
Once beaconing is triggered the interface works as expected and mesh
peer links are automatically established. I assume this is a bug in =20
the rt2x00
driver. Is there anything I can do to help debug this problem?

Thanks,
Antonio Marques
