[rdo-users] Verify Tunnel Traffic

[Todd Leishman]

Hello Javier,
Thank you for your help!  I did as you suggested and used OVN instead of
OVS.  The tunnels now show as correctly configured when I run ovs-vsctl
show.

I don't think I would have figured that out on my own and have made the
suggestion on GitHub to update the documentation.

Again, I appreciate your help.
