This task is tracking the test case writing activities to cover the bug described below.

When running OpenShift's conformance test suite against OpenShift with Open vSwitch's userspace datapaths (proof of concept) then /var/log/openvswitch/ovs-vswitchd.log occasionally logs:

ofproto_dpif_xlate(handler9)|WARN|Invalid Geneve tunnel metadata on bridge br-int while processing tcp,in_port=5,vlan_tci=0x0000,dl_src=0a:58:64:58:00:06,dl_dst=0a:58:64:58:00:05,nw_src=10.128.2.14,nw_dst=10.131.0.3,nw_tos=0,nw_ecn=0,nw_ttl=63,nw_frag=no,tp_src=43400,tp_dst=8443,tcp_flags=syn
