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.
NDR Throughput
~~~~~~~~~~~~~~
Testpmd NDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented
in the graph below.

PDR Throughput
~~~~~~~~~~~~~~
Testpmd PDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented
in the graph below. PDR measured for 0.5% packet loss ratio.
