As I keep saying, you are not supposed to use the IP address as a key to find the netdev, that is the wrong way to use the Linux netdev model. Requiring unique GID/PKey allows the implementation to avoid this wrongness, which would be simplifying and more correct. That is the appeal to blocking this scenario when children are created.
