I also just noticed that the ESA registers (Global 1,2,3)
aren't set at all.  I'm pretty sure that the way I'm using
the switch in my bootloader this doesn't matter as all packets
have a fixed routing and the ESA recognition happens at the
actual ethernet device.

Is this going to cause problems with the VLAN (+DSA) based
routing?
