Title:
  ML2 l2-pop Mechanism driver fails when more than one port is
  added/deleted simultaneously

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron havana series:
  New

Bug description:
  If I create more than one VM at a time (with nova boot option --num-
  instances), sometimes the flooding flow for broadcast, multicast and
  unknown unicast are not added on certain l2 agents.

  And conversely, when I delete more than one VM at a time, the flooding
  rule are not purge on certain l2 agents when it's necessary.

  I made this test on the trunk version with OVS agent.
