OCI state in containerd and cri-o

When trying https://github.com/LionelJouin/network-dra with crio instead of containerd it fails. The reason, or at least the first encountered problem, is that the OCI state differs:

Containerd:

{
  "ociVersion": "1.0.2-dev",
  "id": "f8a629809a08c9b1c45fae0fd34328dc29ece873cbe1ece14aaf35a2e370042b",
  "status": "creating",
  "pid": 1151,

Enable pod-pod multicast in K8s by using multus+ipvlan

Most CNI-plugins doesn't support pod-pod multicast. A way to fix that is to add an ipvlan network using Multus. Howto install Multus and the whereabouts IPAM in you environemt is not in the scope of this gist.

Assuming multus and whereabouts are installed, create a "NAD" for ipvlan on the main K8s network.
