-| ... | 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 either binary search or linear search
-| ... | algorithms with configured starting rate and final step that determines
-| ... | throughput measurement resolution. Test packets are generated by TG on
-| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
-| ... | (flow-group per direction, one flow per flow-group) with all packets
-| ... | containing Ethernet header, IPv4 header with UDP header and static
-| ... | payload. MAC addresses are matching MAC addresses of the TG node
-| ... | interfaces.
