This provides an automated failover mechanism via APIs to create
and destroy a failover master netdev and manages a primary and
standby slave netdevs that get registered via the generic failover
infrastructure. This can be used by paravirtual drivers to enable
an alternate low latency datapath. It alsoenables live migration of
a VM with direct attached VF by failing over to the paravirtual
datapath when the VF is unplugged.
