Detailed Description

This class tests L4S mode.

This test is divided to sub test one without hash collisions and so ECT0 and ECT1 flows are classified into different flows. Sub Test 1 70 packets are enqueued into both the flows with the delay of 0.5ms between two enqueues, and dequeued with the delay of 1ms between two dequeues. Sub Test 2 140(70 ECT0 + 70 ECT1) packets are enqueued such that ECT1 packets are enqueued at 0.5ms, 1.5ms, 2.5ms and so on, and ECT0 packets are enqueued are enqueued at 1ms, 2ms, 3ms and so on Any future classifier options (e.g. SetAssociativehash) should be disabled to prevent a hash collision on this test case.
