That sounds like a datalink, not an interface. Given that the protocol
family is PF_INET/PF_INET6, it seems like the namespace should be objects
in that namespace -- i.e., IPv4 and IPv6 interfaces, not datalinks. (Note
that it is possible (though certainly not recommended) to have a datalink
named foo0 and an interface named foo0 that have no relationship to one
another.)
I'm not sure that I understand what you're trying to say.
Please expand and include an example.
