L2 Ethernet Interface Loop ========================== Following sections include summary graphs of DPDK Testpmd Phy-to-Phy performance with L2 Ethernet Interface Loop, including NDR throughput (zero packet loss) and PDR throughput (<0.5% packet loss). Performance is reported for Testpmd running in multiple configurations of Testpmd pmd thread(s), a.k.a. Testpmd data plane thread(s), and their physical CPU core(s) placement.
