If Stuart is thinking about the Rabbit, then it will never encounter
a hub, and technically there is no requirement to include the port
number I don't think this rule even breaks if a bridge is used to
join two xAP networks operating on different ports. But for
consistency and the sake of uniformity, I think all TCP/IP devices
should.
