This shows a different MAC address for the IBSS.

And I haven't seen any valid comms quality display when running IBSS
mode, though this may be due to different firmware.

It would be interesting to see the result of a '-p 1' under these
circumstances.  Also, it's correct that you're not using a base
station, right?  Otherwise you shouldn't be trying IBSS mode.
