| ... | 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.
