Description of problem:
Unable to establish outbound connection after configuring egress IP for namespace and configuring a NetworkPolicy for that same namespace.

Version-Release number of selected component (if applicable):
3.11

How reproducible:


Steps to Reproduce:
1. Configure hostsubnet egressIP on egress node(this is not the same node where the pod in question is being run)

# oc patch hostsubnet the-node-name -p '{"egressIPs": ["10.x.x.141"]}'

2. Configure netnamespace for the namespace in question with an egressIP

# oc patch netnamespace test-name-space -p '{"egressIPs": ["10.x.x.141"]}'

3. Apply network policy to block incoming traffic to namespace

~~~
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: deny-other-namespaces
  namespace: test-name-space
spec:
  podSelector: null
  ingress:
    - from:
        - podSelector: {}
~~~

4. rsh to the pod and attempt to `curl` external server


Actual results:
`curl` is unable to connect to external server

Expected results:
`curl` is should be able to connect to external server
