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

This patch series enables virtio 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 unplug the VF device from the guest on the source host and reset the MAC filter of the VF to initiate
