Cover letter [PATCH net-next 0/3] net: flush neighbor entries when carrier is off
Commit a6db4494d218c ("net: ipv4: Consider failed nexthops in multipath routes") added support for checking neighbor state when selecting a path for multipath route lookups. It works but incurs a delay waiting for the neighbor entry to timeout. Improve the path selection by flushing non-permanent neighbor entries when carrier is off.
