Additional info:

Problem only happens with the tests referenced below and only in ovs-dpdk environment:

ovs_test_vm_nic ovs_test_vm_multiple_vlans ovs_test_vm_vlan_id0 ovs_test_vm_gre1_ipv6 ovs_test_vm_gre_flow_ipv6 ovs_test_vm_vlan_gre1_ipv6 ovs_test_vlan_mode_access_vm ovs_test_vlan_mode_trunk_vm ovs_test_vlan_mode_native_untagged_vm ovs_test_vlan_mode_native_tagged_vm

- Same tests run with same versions against Mellanox ConnectX6 DX card (mlx5_core) show no problem.
- Same tests run against E810 ice card pass 100% using openvswitch3.1 from FDP 23.F with RHEL-9.2.
- This issue is also seen on these same tests using openvswitch3.2 with RHEL-9.3.

Note: VMs are running RHEL-8.6 instead of RHEL-9.2 due to BZ https://bugzilla.redhat.com/show_bug.cgi?id=2184976 but problem is also seen using RHEL-9.2 VM with RHEL-9.3 which contains the fix for https://bugzilla.redhat.com/show_bug.cgi?id=2184976.
