[RFC PATCH net-next v5 0/4] Enable virtio_net to act as a backup for a passthru device
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
