Bug 1927895

Steps to Reproduce:

Used the yaml files from https://github.com/openshift/app-netutil, specifically from https://github.com/openshift/app-netutil/tree/master/samples/dpdk_app/sriov

In an OCP or Kubernetes cluster with Multus as default CNI, deploy a pod with two SR-IOV VFs, each VF from it's own network. Replace kubectl with oc below if on OCP.

1) Download yaml files:

  git clone https://github.com/openshift/app-netutil.git
  cd app-netutil/samples/dpdk_app/sriov
-- or --
  go get github.com/openshift/app-netutil
  cd $GOPATH/src/github.com/openshift/app-netutil/samples/dpdk_app/sriov


2) If SR-IOV Device Plugin in not deployed, modify config map to match system and then create configMap, then deploy SR-IOV DP:

  vi configMap.yaml 
  kubectl create -f configMap.yaml

  kubectl create -f sriovdp-daemonset.yaml


3) Create the Network Attachment Definition for each VF (if configMap already existed, update Network Attachment Definition to resourceName from existing configMap):

  kubectl create -f netAttach-sriov-dpdk-a.yaml
  kubectl create -f netAttach-sriov-dpdk-b.yaml


4) Create pod that uses the SR-IOV VFs. I was using the dpdk-app-centos image from the app-netutil repo, however, any container will work. Once the Pod comes up, view the annotations associated with the pod.

  kubectl create -f sriov-pod-1.yaml
  kubectl describe pod sriov-pod-1

                        "pci": {
                            "pci-address": "0000:01:02.4"

                }]
              k8s.v1.cni.cncf.io/networks: sriov-net-a, sriov-net-b

From this output, "device-info" for "net1" and "net2" are the same. They should be different.
