33 | ... | *[Enc] Packet Encapsulations:* Eth-IPv4-UDP for LoadBalancer maglev.

35 | ... | maglev and one static IPv4 /24 route entries. DUT1 tested with\
37 | ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
38 | ... | Rate) with zero packet loss tolerance and throughput PDR (Partial Drop\
39 | ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
40 | ... | of packets transmitted. NDR and PDR are discovered for different\
41 | ... | Ethernet L2 frame sizes using MLRsearch library.\
42 | ... | Test packets are generated by TG on links to DUT. TG traffic profile\
43 | ... | contains two L4 flow-groups (maglev use flow-group is only from TG\
44 | ... | to DUT, 6 flows for flow-group) with all packets containing Ethernet\

46 | ... | addresses are matching MAC addresses of the TG node interfaces.
