+| ... | link bonding (mode XOR, transmit policy l34) on link between DUT1 and
+| ... | DUT2 and L2 cross- connect. Qemu Guest is connected to VPP via
+| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting
+| ... | vhost-user interfaces using 5 cores pinned to cpus 5-9 and 2048M memory.
+| ... | Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores (1 main
+| ... | core and 4 cores dedicated for io), forwarding mode is set to io,

+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
+| ... | of packets transmitted. NDR and PDR are discovered for different
+| ... | Ethernet L2 frame sizes using either binary search or linear search
+| ... | algorithms with configured starting rate and final step that determines
+| ... | throughput measurement resolution. Test packets are generated by TG on
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
+| ... | (flow-group per direction, 253 flows per flow-group) with all packets
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
+| ... | payload. MAC addresses are matching MAC addresses of the TG node
+| ... | interfaces.
+| ... | *[Ref] Applicable standard specifications:* RFC2544.
