[Rdo-list] Issues with rdo-release-4 and external networking / br-tun

[uberj]

Found a fix for this:

     rm /etc/sysconfig/network-scripts/ifcfg-br-tun
     (restart neutron networking services and nova-compute)

Apparently that file shound't exist. The flapping may have been due to 
openvswitch and the underlying system fighting for control of the interface.
