| ... | 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, 254 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.
