At this moment we only test KMP on VM's masquerade interface, which is wrong and should be removed (https://issues.redhat.com/browse/CNV-76425) and on secondary multus.
We should test KMP enforced on UDN interfaces - both primary and secondary.
When handling this, also consider covering passt primary interface. Guest's passt interface is supposed to be exposed externally with its unique MAC, so it makes sense that it should also be managed by KMP, but this must be verified before adding this coverage.
