Hi Florian

Yes, it seems it probes ok. The netdevs are made, and the userports goes 
to "forwarding" in the log. But no packet transmission/reception. 
"ifconfig" says that all packets on the CPU side port (FEC) are 
discarded. Otherwise I did not do any debugging. I decided to start by 
having the DTS checked. I guess I will do some more debugging next week.

Thanks a lot
