      This issue is regression of multus functionality so need to fix for 4.14, otherwise 4.14 miss one of the

      Marko Luksa mentioned multus missing '/etc/cni/multus/net.d' mount in OCP4.14 and here's the repro step (verivied in multus team)

      Our original reproducer would be too complex, so I had to write a simple one for you:
      Use a 4.14 OpenShift cluster
      Create the CNI plugin installer DaemonSet in namespace test:

      oc apply -f https://gist.githubusercontent.com/luksa/c4d444e918124604839c424339c29a62/raw/1454bd389138980ea3f93bcfaf6026d4821e3543/noop-cni-plugin-installer.yaml

      Create the test Deployment:

      oc apply -f https://gist.githubusercontent.com/luksa/4c7c144ef88b1b0d8f772d6eacdeec14/raw/06b161fdb8c71406f4531d35550bd507a6a25200/test-deployment.yaml

      Describe the test pod:

      oc -n test describe po test

      The last event shows the following:

      ERRORED: error configuring pod [test/test-6cf67dcfb6-hgszq] networking: Multus: [test/test-6cf67dcfb6-hgszq/3e8a6f0d-ce84-4885-a7a7-43506669339f]: error loading k8s delegates k8s args: TryLoadPodDelegates: error in getting k8s network for pod: GetNetworkDelegates: failed getting the delegate: GetCNIConfig: err in GetCNIConfigFromFile: No networks found in /etc/cni/multus/net.d

      The same reproducer runs fine on OCP 4.13
