*BSD should only ever expose the outside addresses of the GRE tunnel via 
the gre(4) specific interface ioctls, it is not part of the sysctl 
interface MIB or the routing socket messages there.

Clearly this issue is specific to the Linux interface handling code. I 
was under the impression though that Netlink used a TLV message format, 
so it's possible the relevant fields are in another TLV.
