The most recent user-space code in vswitchd that deals with the L3
tunnels in netdev and kernel datapath is contained in another patch
series:
https://mail.openvswitch.org/pipermail/ovs-dev/2017-February/328391.html
You could help in reviewing that. It may not be complete with respect to
handling kernel datapath tunnels as we were not able to test yet due to
a lack of patches to configure L3 tunnel ports in the kernel. But
similar problems with counters might also exist with netdev datapath.
Thanks, Jan
