I believe there is a difference between being a router and merely
being capable of forwarding IP packets. To me, a router participates
in a routing protocol and/or advertises routes/prefixes. So perhaps
Hadmut has a valid point that autoconfiguration should not depend
on ip_forward being off, although I'm not sure what the appropriate
alternate test for not being a router should be.
