Title:
  Agent API gets broken if OVN DB is upgraded to the one introducing
  chassis_private

Status in neutron:
  Fix Released

Bug description:
  Neutron determines which table to use for agent healthchecks at the
  initialization phase. With OVN databases that don't implement
  chassis_private table a chassis table is used, which has scaling
  impacts.

  However, if OVN DB is upgraded while Neutron is running, the
  healthchecks will be still performed on chassis table while OVN
  already uses chassis_private. This leads to reporting dead agents by
  the API.

  We should detect OVN was upgraded and start using chassis_private
  table since.
