neigh: probe application via netlink in NUD_PROBE iproute2 arpd seems to expect this as there's code and comments to handle netlink probes with NUD_PROBE set. It is used to flush the arpd cached mappings. opennhrp instead turns off unicast probes (so it can handle all neighbour discovery). Without this change it will not see NUD_PROBE probes and cannot reconfirm the mapping. Thus currently neigh entry will just fail and can cause few packets dropped until broadcast discovery is restarted.
