We're getting a bit away from the original topic, but this is still a
useful discussion. This explains a lot.  We've got the ethX devices
which are the physical device, same as any non-Xen system, and the
xenbrX devices, which are the actual bridges. The pethX devices don't
seem to serve any real purpose. I would hazard a guess that the pethX
devices aren't really needed at all, and are just there for historical
compatibility.
