If you could please re-test with -pre13 and Large Send enabled again it
would be useful. If that goes at full speed then I don't really need the
info from xenstore-ls, but if it goes slowly again I would appreciate
the xenstore-ls info.

It may be that your netback is telling the drivers that large send is
unsupported but that I'm activating it anyway, which may well result in
a slowdown.

Thanks
