+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.

+CSIT test cases used to generate results presented above can be found in CSIT
+git repository by filtering with specified regex as follows:
