Help text

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 also enables live migration of a VM with direct attached VF by failing over to the paravirtual datapath when the VF is unplugged.
