Description of problem:
Create Pod using annotation contains empty named network interface, the chart color and value does not match.

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-08-25-204643

How reproducible:
Always

Steps to Reproduce:
1. Create a cni NetworkAttachmentDefinition for a project:
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
  name: ipvlan-host-local
spec:
  config: '{
        "cniVersion": "0.3.1",
      "name": "ipvlan-host-local",
      "master": "ens5",
      "type": "ipvlan",
      "ipam": {
             "type": "host-local",
             "subnet": "22.2.2.0/24"
}
}'

2. Create a pod:
apiVersion: v1
kind: Pod
metadata:
  name: pod-ipvlan-host-local
  annotations:
    k8s.v1.cni.cncf.io/networks: ipvlan-host-local
spec:
  containers:
  - name: pod-name
    image: quay.io/openshifttest/multus-pod@sha256:48da37205f9b43424e0983d4c5e7e07f77b7ba1504bbe35e2f264c75dcb4cd15

3. Check the annotation for the pod which contains empty value here： 
$oc get pod pod-ipvlan-host-local -o json|jq .metadata.annotations

annotations:
    k8s.v1.cni.cncf.io/network-status: |-
      [{
          "name": ""


Actual results:
The Network Output chart has wrong tooltip interface hightlight color. (please check the screenshot. Color for interface with name value is yellow which is the Total, it should be blue according to the chart)

Expected results:
There should show either 2 interfaces and tooltip match values independently and correctly, or only one interface to show the correct tooltip color with matched value in chart.
