Public bug reported:

If OVSBridge.get_ports_attributes is executed on an empty bridge,
get_port_name_list will return an empty string. In which case,
ovsdb.db_list is executed with port_names = '', meaning that it will
return all ports, instead of no ports.

The implication is that if, for example, br-ex (An ancillary bridge in
the OVS agent) is currently empty, then scan_ancillary_ports will pick
up all ports. All ports on the system will be considered
ancillary_ports, which is unexpected and can result in ports going DOWN
when they shouldn't.
