Add a test that runs traffic across a port throttled with TBF. The test checks that the observed throughput is within +-5% from the installed shaper. To allow checking both the software datapath and the offloaded one, make the test suitable for inclusion from driver-specific wrapper. Introduce such wrappers for mlxsw.
