Looks like the test is racing with a port detach cleaning up the vif entry from the network info cache:

@Matt: your observation seems correct. During the deallocate_port_for_instance() call the _unbind_ports() call[1] removes the information from the binding:profile but the allocation only removed from placement after deallocate_port_for_instance() so waiting for the binding:profile cleanup in the test can case the race.

Fortunately interface_detach.end notification emitted after deallocate_port_for_instance() so the test can wait for the notification instead.

    fix race in test_interface_detach_with_port_with_bandwidth_request

    During port detach the unbind towards neutron happens before the
    port allocation is removed from placement. The functional test only
    waited for the port unbind before asserted the remaining allocations and
    therefore it was racy.

    Fortunately the instance.interface_detach.end is emitted after the both
    the unbind and the allocation shrink. So the test is changed to wait for
    this notification instead.
