Nick Brown b8b43f70c8 Send ICMP errors when link address resolution fails ... Before this change, we would silently drop packets when link resolution failed. This change brings us into line with RFC 792 (IPv4) and RFC 4443 (IPv6), both of which specify that gateways should return an ICMP error to the sender when link resolution fails.
