Yes, but presumably if it's acting as a bridge, most of the traffic is
going straight across rather than going to/from the IP address of the
bridge (iftop uses the IP address as a fall back in the event that it
can't get the hardware address, but for this reason h/ware address is
preferred).

Hmm.  Can you tell me what iftop says about the hardware address for the
interface?  My guess is that for some reason it can determine h/ware
address for 10baseT/UTP.
