+| ... | routing and static route, SR policy and steering policy for one\

+| ... | other direction. DUT1 and DUT2 are tested with 2p10GE NIC X520 Niantic\

+| ... | *[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, 253 flows per flow-group) with\
+| ... | all packets containing Ethernet header,IPv6 header with static payload.\
+| ... | MAC addresses are matching MAC addresses of the TG node interfaces.
