Hi Jeremy!

Well, the physical interfaces only had RX on. The virtual interfaces in 
Dom0 and DomU had RX, TX, SG, TSO and GSO on. Trying to switch off RX on 
the virtual interfaces produced an error message, but after switching off 
the other features, RX was off as well.

But after everything was off (in Dom0 bridge eth0 with peth0 and vif1.0 
and bridge xenbr1 with eth1 and vif1.1 and in DomU eth0 and eth1), the 
setup didn’t start working. So if this is some kind of checksum problem, 
switching the checksum and offload features off don’t change it.

Do you have other suggestions?

I hope so. Anf if there are patches to test, I will test it.

Shade and sweet water!
