when sriov is enabled, the pod will have multiple interfaces, to select the sriov interface for the test, you may want to 
change the test script to identify the sriov ip address used by the uperf slave pod. Right now the slave pod default 
ip address is used in the script: slave=$(oc get pods uperf-slave -o json | jq -r '.status.podIP')
