Good, this indicates that the speed got changed, which means we can
concentrate on making sure the sires table is set up right.

And let's go ahead and just get the wires table set up without worrying
about switchmac, since there are so few wires...

For now, let's just get the 'Node' wires right.

All should have 'card2' set to '1', as you do have. Set 'port2' to
whatever number the port is marked as having on the switch itself (eg.
the number that's printed on the faceplate of the switch).
