Hi,

in OpenStack Neutron project we use Open vSwitch on a single node to simulate tunneling between multiple nodes. After commit [1] was merged, we observe openflow output rule being applied on packets, that injects packets into tunnels but we don't see any packets on the other side of the tunnel.

I wrote a simple script to build this environment in order to make it easy to reproduce [2]. I didn't attach it, I can if requested.

Ways to reproduce:
   - fetch the script (e.g. fullstack_env.sh)
   - run as root: fullstack_env.sh setup
   - try ping via tunnel: ip net e nsA ping 10.20.0.10

In previous OvS 2.4 were icmp replied.
