During a fresh deployment of a MNO using ZTP for a telco partner, for which we configure some NetworkAttachDeffinitions of MACVLAN kind, we realized that the the current method is not allowed anymore. We usually create these NADs using the CR cluster.networks.operator.openshift.io .

We have a manifest from where we create two NADs with the same name but different namespace. When we try to apply this manifests we have log below.

The Network "cluster" is invalid: spec.additionalNetworks[3]: Duplicate value: map[string]interface {}{"name":"nad-net0"}
