A so-called "MC-aware" mode has recently been enabled in mlxsw. In MC-aware mode, BUM traffic is handled in a special way so that when a switch is flooded with BUM, UC performance isn't unduly impacted. Without enablement of this mode, a stream of BUM traffic can cause sustained UC throughput drop in excess of 99 %. Add a test for this behavior. Compare how much UC throughput degrades as a stream of broadcast frames floods the switch. A minimal degradation is tolerated to cover for glitches in traffic injection performance. Signed-off-by:
