The main motivation for this patch is to enable cloud service providers to provide an accelerated datapath to virtio-net enabled VMs in a transparent manner with no/minimal guest userspace changes. This also enables hypervisor controlled live migration to be supported with VMs that have direct attached SR-IOV VF devices. Patch 1 introduces a new feature bit VIRTIO_NET_F_BACKUP that can be used
