| ... | interconnecting vhost-user interfaces using 5 cores pinned to cpus 5-9
| ... | and 2048M memory. Testpmd is using socket-mem=1024M (512x2M hugepages),

| ... | formula: ref-PDR = 0.9x PDR, where PDR is found in RFC2544 long
| ... | performance tests for the same DUT configuration. 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.
