...which means that the TCP reassembly code should, arguably, use both
the addresses *AND* the port numbers when looking up stuff, although
that means it couldn't just use "fragment_add()".

Another possibility would be to have the TCP reassembly code always use
absolute sequence numbers; it might also make sense to have it *display*
both the absolute and relative sequence numbers (and ack numbers and
next sequence numbers) if relative port numbers are requested.
