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
