.. note::
(1) Max burst parameter is skipped because it is not supported by the
IP tool.
(2) Only for physical bridges (tenant networks, provider networks), tunneled
traffic is not shaped yet.
(2) Placement based enforcement works for both egress and ingress directions,
but dataplane enforcement depends on the backend.
