James,

It worked, thanks.

I will leave the exact command here to maybe help somebody that is as 
confused as I was.
I'm using Xen on Debian, so the physical interface is named pethN, so 
the command is:
ethtool -K peth0 tx off gso on

James, I'm still curious to know why things work when the server is in 
Dom0, is there a reason for that?
Thanks.

Fábio Catunda.
