[RFC PATCH v3 0/3] Enable virtio_net to act as a backup for a passthru device
Patch 1 introduces a new feature bit VIRTIO_NET_F_BACKUP that can be
used by hypervisor to indicate that virtio_net interface should act as
a backup for another device with the same MAC address.
Ppatch 2 is in response to the community request for a 3 netdev
solution. However, it creates some issues we'll get into in a moment.
It extends virtio_net to use alternate datapath when available

[RFC PATCH net-next v6 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.
