   1 L2 Ethernet Switching
   2 =====================
   3
   4 This section provides a summary of VPP Phy-to-Phy L2 Ethernet switching
   5 performance illustrating packet latency measured at 50% of discovered NDR
   6 throughput rate. Latency is reported for VPP running in multiple
   7 configurations of VPP worker thread(s), a.k.a. VPP data plane thread (s), and
   8 their physical CPU core(s) placement.
   9
  10 Title of each graph is a regex (regular expression) matching all plotted
  11 test case throughput measurements.
