I'd prefer IFLA_PEER. More generic attribute will be helpful should we
introduce an interface similar to veth in the future.

Also, I'd not combine IFLA_LINK_NETNSID with IFLA_PEER. There might
very well be an interface in the future that will need both IFLA_LINK and
IFLA_PEER and this would just create a confusion. It may be unlikely
but the attributes are cheap and it doesn't make sense to design uAPI
in a way that might bring problems in the future.

Apparently we need to pick our poison. Either way, we break something.
