Log message:
Implement link-state tracking on the routing table. Routes to interfaces
which are considered down will no be marked ~RTF_UP and so multipath routing
will start to work as expected and not pump 50% of the traffic to nirvana.
Most of the magic happens in rn_mpath_reprio() which fiddles with the
routing table internals. The rest is more straight forward.
