This patch series extends virtio_net to take over VF datapath by simulating a transparent bond without creating any additional netdev. I understand that there are some comments suggesting an alternate model that is based on 3 driver model(virtio_net, VF driver, a new driver virt_bond that acts as a master to virtio_net and VF). Would like to get some feedback on the right way to solve the live

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

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
