The ops12are used as event handlers that get called to handle netdev register/13unregister/link change/name change events on slave pci ethernet devices14with the same mac address as the failover netdev.15 16This enables paravirtual drivers to use a VF as an accelerated low latency17datapath. It also allows live migration of VMs with direct attached VFs by18failing over to the paravirtual datapath when the VF is unplugged.19
