| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
| ... | Rate) with zero packet loss tolerance and 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 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, IPv6 header with IP\
| ... | no next header and static payload. MAC addresses are matching MAC\
| ... | addresses of the TG node interfaces.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
