parentipv4: Cache routes in nexthop exception entries. (diff)
ipv4: Properly purge netdev references on uncached routes.
When a device is unregistered, we have to purge all of the references to it that may exist in the entire system. If a route is uncached, we currently have no way of accomplishing this. So create a global list that is scanned when a network device goes down. This mirrors the logic in net/core/dst.c's dst_ifdown(). Signed-off-by: David S. Miller <davem@davemloft.net>
