Usage: Run for 10us, check rxMaster - all 3 packets have passed through Purpose: This TB checks the what happens when a packet arrives immediately after the previous one. It generates 3 packets directly to the RX XGMII interface. Delay between packets 1 and 2 is 3 clock cycles, and 0 between packets 2 and 3. Simulation is successful if all 3 packets are passed onto rxMaster stream.
