-| ... | IP protocol=61 and random payload. Ethernet header MAC addresses are

+| ... | connect. DUT1 and DUT2 tested with 2p10GE NIC X520 Niantic by Intel.
+| ... | *[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
