[PATCH net-next 0/3] net: flush neighbor entries when carrier is off

[David Ahern <dsahern@gmail.com>]

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.
