This adds mergeable buffers support in vhost-net in qemu. With this patch, sending raw packets while vhost-net is active should work as well: important for migration. Compile-tested only for now. David, could you please review and maybe try this out? The kernel side is in vhost-net-next. I intend for it to got into net-next and then into 2.6.36.
