'no link' here, so please check your magnetics and RJ-45 connector.
I found the problem. I did a wrong connection (PCB) between common line
of the magnetics to the ethernet-vcc line. This line has to be connected
ONLY to the GND with a single 10nF capacitor only.
When connecting to a Gigabit Ethernet switch:
barebox@EK360 Eurek i.MX6 Quad:/ dhcp
warning: No MAC address set. Using random address 8e:0c:97:9d:0d:fd

When connecting to a 100Mb Ethernet switch:
barebox@EK360 Eurek i.MX6 Quad:/ dhcp
warning: No MAC address set. Using random address 2e:a7:4d:11:f2:65

Right now, I have no 10Mb HUB but who cares? I will face the problem (if
any) when somebody will point me this issue... ;-)
I would to thank everybody on the mailing list for all hints!
The next step is to calibrate the skew-rate of the lines (if needed)
when facing some problems during high load transfer in both modes
(100/1000) but for this I need to boot up in Linux first.
Next step is to connect a USB Disk and try to mount it...
Stay tuned! ;-)
Best regards,
Gianluca
