[Bug 1461519] [NEW] Enabling ml2 port security extension driver causes net-list to fail on existing deployment

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I had a kilo setup where there were a few existing networks.  Then I
enabled the port security extension driver in ml2_conf.ini.

After this net-list fails because the extension driver tries to access
the fields(port security related) which were never set for the old
networks.
