| ... | *[Enc] Packet Encapsulations:* Eth-IPv4-UDP for IPv4 routing.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with IPv4\

| ... | static IPv4 /28 and IPv4 /24 route entries on DUT2. DUT1 and DUT2\
| ... | tested with ${nic_name}.
| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
| ... | Rate) with zero packet loss tolerance and 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 MLRsearch library.\
| ... | Test packets are generated by TG on\
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
| ... | (flow-group per direction, one flow per flow-group) with all packets\
| ... | containing Ethernet header, IPv4 header with UDP header and static\
| ... | payload. MAC addresses are matching MAC addresses of the TG node\
| ... | interfaces.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
