Comment 19 for bug 1864822

I'm not sure if this DROP rule is really a culprit of the issue.
It comes from: https://github.com/openstack/neutron/blob/stable/stein/neutron/plugins/ml2/drivers/openvswitch/agent/ovs_neutron_agent.py#L1376 so it is installed every time when phyical bridge is configured.
I checked on my local env with devstack and I also have such rule:

cookie=0xf8e18c7feb8a151, duration=13.960s, table=0, n_packets=0, n_bytes=0, idle_age=14, priority=2,in_port=1 actions=drop

but it doesn't causes any problems.
In Your logs from last comment, I also see that number of packets matched for that drop rule is 0.

And also, even when I'm restarting openvswitch-switch process, I can't reproduce this issue with flows on my env. But I'm doing it on master branch. Tomorrow I will try on stable/Stein.
Can You also tell me if You have e.g. dvr enabled in this setup? Or anything else which may help me to reproduce that.
