What firmware revision you have? Since you are saying nothing
transmitted as well, I doubt if you have a link. Otherwise I
would imagine kernel tries to send some neighbor solicitation
crap as soon as you bring up interface. What does your
"ethtool ethx" say about the link? 

It's possible to bisect commits which applied in driver/net/netxen.
That way you have fewer commits to rewind and remains focused on
the driver rather than screwing scsi.

Thanks,
Dhananjay
