Following patch restructures ovs tunneling and gre vport implementation to make ovs tunneling more in sync with upstream kernel tunneling. Doing this tunneling code is simplified as most of protocol processing on send and recv is pushed to kernel tunneling. For external ovs module the code is moved to kernel compatibility code.
