[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

[RFC PATCH net-next v5 3/4] virtio_net: Extend virtio to use VF datapath when available
This patch enables virtio_net to switch over to a VF datapath when a VF netdev is present with the same MAC address. It allows live migration of a VM with a direct attached VF without the need to setup a bond/team between a VF and virtio net device in the guest. The hypervisor needs to enable only one datapath at any time so that packets don't get looped back to the VM over the other
