If the ethtool output you provided is with the USRP2 plugged in and
turned on, then your ethernet card isn't detecting a link. If another
computer works fine with that same USRP2, I suspect the ethernet cable
or your ethernet card as the culprit. You might also try:
sudo ifconfig eth0 up
and see if that affects the result of your ethtool output.
