+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with two L2
+| ... | bridge domains and MAC learning enabled. LXC is connected to VPP via
+| ... | Memif interface. LXC is running same VPP version as running on DUT. LXC
+| ... | is limited via cgroup to use 3 cores allocated from pool of isolated
+| ... | CPUs. There are no memory constraints. 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
+| ... | 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, IPv4 header with IP protocol=61 and static
+| ... | payload. MAC addresses are matching MAC addresses of the TG node
+| ... | interfaces.
