[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

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
