OK.  If you try to cheat the gianfar driver by having it attach to
the PHY for lan1.1, and plug a network cable into lan1.1 so that the
link goes up and gianfar thinks that the link on eth0 is up, does that
enable you to pass packets over any of the switch interfaces?  That
should be working now in this stage.
