Updated version pushed to: 
  git://xenbits.xen.org/people/ianc/linux-2.6.git upstream/dom0/backend/netback

Still a WIP. Next step is to look at how to get rid of xenvif_copy_skb
(previously netbk_copy_skb), either by making it unnecessary or by
generalising it for the net core.

There are a couple of changes which touch netfront here: completing the
namespacing of include/xen/interface/io/netif.h (the netif prefix is
reserved for core code) and improvements to the Kconfig help. I guess it
would be best to split those and send out first.

Ian.
