net/core: add NETDEV_BONDING_FAILOVER event
Add NETDEV_BONDING_FAILOVER event to be used in a successive patch by bonding to announce fail-over for the active-backup mode through the netdev events notifier chain mechanism. Such an event can be of use for the RDMA CM (communication manager) to let native RDMA ULPs (eg NFS-RDMA, iSER) always be aligned with the IP stack, in the sense that they use the same ports/links as the stack does. More usages can be done to allow monitoring tools based on netlink events being aware to bonding fail-over.
