-L2 Ethernet Interface Loop
-==========================
-
-This section includes summary graphs of Testpmd Phy-to-Phy packet
-latency with L2 Ethernet Interface Loop measured at 50% of discovered
-NDR throughput rate. Latency 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.
-
-Testpmd packet latency - running in configuration of **one worker thread (1t) on one
-physical core (1c)** - is presented in the figure below.
