ipv4: fib: Notify about nexthop status changes
When a multipath route is hit the kernel doesn't consider nexthops that are DEAD or LINKDOWN when IN_DEV_IGNORE_ROUTES_WITH_LINKDOWN is set. Devices that offload multipath routes need to be made aware of nexthop status changes. Otherwise, the device will keep forwarding packets to non-functional nexthops. Add the FIB_EVENT_NH_{ADD,DEL} events to the fib notification chain, which notify capable devices when they should add or delete a nexthop from their tables.
