Flow of calls:
1. functional test creates network in Neutron API
2. OVN ml2 mechanism adds the required Logical_Switch
3. ovn-northd gets the data and creates datapath_binding in OVN SBDB.
4. Test reads the value of datapath_binding from OVN SBDB

The problem described in this bug its race-condition between 3 and 4.

In fact, based on the logs, I can find that the datapath_binding was created in SBDB, but functional test was *too fast* in reading it.
Found entry from SBDB:
