ACNP IngressPolicy not working for Flexible IPAM pods

[KMAnju-2021]

Describe the bug

acnp ingress policy not working only for one case in kind cluster: when src Pod is IPAM-pod without vlan and destination pod is IPAM-pod with vlan (11,12).

To Reproduce

1. create kind cluster
2. apply antrea.yml with enableIPAM feature.
3. apply ingress acnp

apiVersion: crd.antrea.io/v1beta1 kind: ClusterNetworkPolicy metadata: name: acnp-with-drop-a spec: priority: 1 appliedTo: - podSelector: matchLabels: pod: a ingress: - action: Drop from: - podSelector: {} enableLogging: true

4. Run TestAntreaIPAMAntreaPolicy/TestGroupNoK8sNP/Case=ACNPIngressDrop test

Expected

destination pod should drop the packets

Actual behavior

kubectl exec -it antrea-ipam-testa-cf59ccc97-bq5w9 -n antrea-ipam-test -- sh Defaulted container "c80" out of: c80, c81, c8080, c8081, c8082, c8083, c8084, c8085 / # curl 192.168.242.100:81 curl: (1) Received HTTP/0.9 when not allowed
