Hi Tomas
Would these problems also explain why the Ethernet links to the switch
don't work? Maybe the differential pairs?

I think there is a known phylib problem here. Somewhere in the call
chain there is a void function, so the EPROBE_DEFFER gets
discarded. But i could be remembering this wrongly.
