Yes. I separated this into 2 parts because the first one (datapath changes) is just to bring the in-tree module into line with netdev net-next. The second part contains the user-space changes and unit tests. There are some comments marked with "XXX" to invite close scrutiny.
If this approach is accepted then I can follow up with further enhancements to report on QinQ, NAT, 64-bit tunnel keys, and to improve the monitoring of Geneve and STT. That should all be pretty straightforward now. No further changes to datapath required.
