Right, I'd expect this sort of network traffic scheduling/shaping to be
achievable with the normal Linux facilities for doing such things (i.e.
tc and friends) and if not then it is those which should be enhanced
rather than adding Xen specific stuff to netback (or else a convincing
reason for it being Xen specific should be given).

The same goes for the other possible backend OSes, e.g. *BSDs
shaping/filtering facility, whatever it is called, should be used there.
