I have a similar situation with my nick on a tower system.

I need to change at least one flag on the card to have it working, I can
also just set the flag to the value it already has.

I'm using a small startup script which actually does this:

start_cmd="ifconfig ${refix_if} tso"

it's similar hardware, same chip, different revision. I already reported
this on net@ but no patch could really solve the issue.
