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

This is another update based on feedback from MST and Stephen on the last patchset. Hopefully this series can be integrated and any further enhancements can be made on top of this patchset. v8: - Made the failover managment routines more robust by updating the feature bits/other fields in the failover netdev when slave netdevs are registered/unregistered. (mst) - added support for handling
