10 The failover module provides a generic interface for paravirtual drivers
11 to register a netdev and a set of ops with a failover instance. The ops
12 are used as event handlers that get called to handle netdev register/
13 unregister/link change/name change events on slave pci ethernet devices
14 with the same mac address as the failover netdev.
16 This enables paravirtual drivers to use a VF as an accelerated low latency
17 datapath. It also allows live migration of VMs with direct attached VFs by
18 failing over to the paravirtual datapath when the VF is unplugged.
