1.create the SR-IOV NetworkNodePolicy:

apiVersion: sriovnetwork.openshift.io/v1
kind: SriovNetworkNodePolicy
metadata:
  name: pci-sriov-net-f1
  namespace: openshift-sriov-network-operator
spec:
  resourceName: pci_sriov_net_f1
  nodeSelector:
    node-role.kubernetes.io/master: ""
  mtu: 1500
  numVfs: 8
  deviceType: netdevice
  nicSelector:
    vendor: "8086"
    deviceID: "1593"
    pfNames: ["ens2f2#0-1"] 

2. Create sriovNetwork 

apiVersion: sriovnetwork.openshift.io/v1
kind: SriovNetwork
metadata:
  name: sriov-net-f1
  namespace: openshift-sriov-network-operator
spec:
  networkNamespace: ztp-testns
  resourceName: pci_sriov_net_f1
  vlan: 150


3. Create pod with interfaces in the network created above

---
apiVersion: v1
kind: Pod
metadata:
  annotations:
    k8s.v1.cni.cncf.io/networks: '[{"name": "sriov-net-f1", "interface": "f1c", "namespace": "ztp-testns" }, {"name": "sriov-net-f1", "interface": "f1u", "namespace": "ztp-testns" }]'
  name: dpdk
  namespace: ztp-testns
spec:
   containers:
   - env:
     - name: service_name
       value: dpdk
     command: ["sleep", "infinity"]
     image: registry.kni-qe-0.lab.eng.rdu2.redhat.com:5000/dpdk
     imagePullPolicy: IfNotPresent
     securityContext:
       runAsUser: 0
       capabilities:
         add: ["IPC_LOCK","SYS_RESOURCE","NET_RAW"]
     name: dpdk
     ports:
     - containerPort: 8080
       protocol: TCP
     resources:
       limits:
         hugepages-1Gi: "4Gi"
         cpu: "4"
         memory: "1Gi"
       requests:
         hugepages-1Gi: "4Gi"
         cpu: "3.8"
         memory: "1Gi"
     volumeMounts:
     - mountPath: /dev/hugepages
       name: hugepage
       readOnly: False
   volumes:
   - name: hugepage
     emptyDir:
       medium: HugePages 

4. Check interface status inside the pod

oc -n ztp-testns exec dpdk -- ip a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0@if2922: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1400 qdisc noqueue state UP group default 
    link/ether 0a:58:2b:3c:0a:a3 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet6 fd01:0:0:1::ac8/64 scope global 
       valid_lft forever preferred_lft forever
    inet6 fe80::858:2bff:fe3c:aa3/64 scope link 
       valid_lft forever preferred_lft forever
143: f1c: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 76:0d:a3:bd:66:fc brd ff:ff:ff:ff:ff:ff
144: f1u: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 26:f5:ce:ec:ce:65 brd ff:ff:ff:ff:ff:ff

f1c and f1u interfaces do not report NO-CARRIER

Attaching sr-iov must gather.
