+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
+| ... | 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, 1M flows per flow-group) with all packets
+| ... | containing Ethernet header, IPv6 header withq IP and static payload.
+| ... | MAC addresses are matching MAC addresses of the TG node interfaces.
+| ... | Incrementing of IP.dst (IPv6 destination address) field is applied to
+| ... | both streams.
