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 is another update based on feedback from MST and Stephen on the last patchset. Hopefully this series can be integrated and any further enhancements can be made on top of this patchset. v8: - Made the failover managment routines more robust by updating the feature bits/other fields in the failover netdev when slave netdevs are registered/unregistered. (mst) - added support for handling

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_STANDBY that can be used
