| ... | 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, rxd/txd=1024,

| ... | 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 MLRsearch library.
| ... | Test packets are generated by TG on

| ... | (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.
