An explicit feature isn't really necessary though given those three right?
An attacker with root on a VM can fake a MAC and IP, but they can't
plug the VM into a different vswitch port...
I guess a database feature could be added that makes it so the three
must be bound in order for flows not to get dropped. But I guess that
would be more important with migration of VMs and then it gets into
a more sophisticated controller like NOX probably right?
