My limited IB experience has been that the IB switch acts much like a dumb
ethernet switch, caring only about which IB hardware addresses are
reachable via which port. Routing between IPoIB and IP over ethernet can
be done by any host with interfaces on both networks and IP forwarding
enabled. In our setups, we've used IPoIB, but with 1918 addresses and not
routed beyond the IB network.
