This provides a generic interface for paravirtual drivers to listen for netdev register/unregister/link change events from pci ethernet devices with the same MAC and takeover their datapath. The notifier and event handling code is based on the existing netvsc implementation. It exposes 2 sets of interfaces to the paravirtual drivers. 1. existing netvsc driver that uses 2 netdev model. In this

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
