| ... | 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

| ... | 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 MLRsearch library.\
| ... | 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, RFC7348.
