If you used the Stein release, you will probably have OVN by default instead of OVS, so the docs will need some update (you can propose the change yourself by clicking on the "Edit on GitHub" ribbon if you are interested). 

In that case, you should have set CONFIG_NEUTRON_OVN_TUNNEL_IF=ens2f1 instead. 

For OVN, you can check the tunnels running "ovs-vsctl show". If the command shows some ports like the following: 

Port "ovn-e9d95c-0" 
Interface "ovn-e9d95c-0" 
type: geneve 
options: {csum="true", key=flow, remote_ip=""} 

With remote_ip being the IP of another machine, then the tunnel is set up correctly.
