You mentioned that "ethtool -k" didn't work in dom0 on eth0, but did you
try it on vif31.0 (or whatever other virtual interface you have) and the
eth0 within your domU? I don't remember which interfaces you're supposed
to be able to perform this operation on, but try executing the disable
transmit checksum offloading command ("ethtool -K eth0 tx off") on
*every* possible interface in your dom0 and domU and see if that helps
you isolate where the problem is.
