Please ask questions in discuss at openvswitch.org. Also, you are asking
questions about a feature that does not exist on the OVS master. It is very
unlikely that you will get any answers on these questions. Based on your
questions over the last few days, I suggest that you spend time with how
OVS works without GTP before embarking on getting GTP to work.
