41| ... | of packets transmitted. NDR and PDR are discovered for different\

43| ... | Test packets are generated by TG on links to DUTs. TG traffic profile
44| ... | contains two L3 flow-groups (flow-group per direction, 254 flows per
45| ... | flow-group) with all packets containing Ethernet header, IPv4 header
46| ... | with IP protocol=61 and static payload. MAC addresses are matching MAC
47| ... | addresses of the TG node interfaces.
