SETUP:

ovs_version: "2.6.1"
ODL snapshot: distribution-karaf-0.6.2-20170803.213544-260
features installed: odl-netvirt-openstack

STEPS to reproduce:

1. start with a clean OVS
2. start a fresh ODL and install netvirt
3. set-manager of OVS to ODL
4. confirm that br-int is created and pipeline flows are correctly installed
5. stop ODL
6. manually delete br-int
014bd065-2822-4ab4-bfc5-4327a5646a81
Manager "tcp:192.168.254.33:6640"
ovs_version: "2.6.1"
7. restart ODL
8. br-int is automatically recreated but pipeline flows are not correct. There are missing flows (a table=213 flow and a table=243 flow are missing), and most of the flows appear to have an incorrect "actions=drop" configuration.

workaround
9. if after step 8., the openvswitch daemon is restarted (e.g.via "systemctl restart openvswitch"), the pipeline flows are reinstalled correctly.

notes:
if at step 6., br-int was not deleted but all its flows were removed, then the pipeline flows are correctly installed after ODL restarts (step 7.).
