Default xen and tcp checksumming

We continue to have sporatic tcp checksum issues in xen (known issue in
xen, I think its even in their FAQ)

I'd like to disable the hardware checksumming:

ethtool -K eth0 tx off

in rc.local. Its not actively causing issues but it is causing
inefficient transfers in some cases. I'd like to do this before the
freeze. Anyone have any problems with that?
