Title:
  Neutron migration to Juno breaks router functionality if ports in
  tenant other than router

Status in neutron:
  Expired

Bug description:
  During recent upgrade from Icehouse to Juno, we lost all interfaces on
  the backside of the router. Plugging the appropriate values into the
  neutron.routerports table corrected the issue.

  From /usr/local/lib/python2.7/dist-packages/neutron/db/migration/alembic_migrations/versions/544673ac99ab_add_router_port_table.py , I find the SQL statement to populate the routerports table:
  ...
  SQL_STATEMENT = (
      "insert into routerports "
      "select "
      "p.device_id as router_id, p.id as port_id, p.device_owner as port_type "
      "from ports p join routers r on (p.device_id=r.id) "
      "where "
      "(r.tenant_id=p.tenant_id AND p.device_owner='network:router_interface') "
      "OR (p.tenant_id='' AND p.device_owner='network:router_gateway')"
  )
  ...

  Running the same statement reflects the status of the routerports
  table when the issue was discovered:

  MariaDB [neutron]> select p.device_id as router_id, p.id as port_id, p.device_owner as port_type from ports p join routers r on (p.device_id=r.id) where (r.tenant_id=p.tenant_id AND p.device_owner='network:router_interface') OR (p.tenant_id='' AND p.device_owner='network:router_gateway');

  Removing tenant_id from the WHERE clause seems to be what should have happened. Not sure why we care what the tenant_id is:
