How reproducible:

Steps to Reproduce:
1. Setup multinode env with openshift-ovs-networkpolicy plugin
2. Create two projects with pod
3. Add the annotation to project 1
# oc annotate namespace u1p1 net.beta.kubernetes.io/network-policy='{"ingress":{"isolation":"DefaultDeny"}}'
4. Apply the network policy to allow the specific port to be accessed
# oc create -f networkpolicy.yaml
cat networkpolicy.yaml
kind: NetworkPolicy
apiVersion: extensions/v1beta1
  name: allow-8080
  - ports:
    - protocol: tcp
      port: 8080

5. Try to access the pod with port 8080 via other pod in project u1p1
6. Try to access the pod with port 8080 via pod in other project

Actual results:
Both step 5 and 6 failed.

Expected results:
The pod in project u1p1 should be able to access via port 8080.
