| ... | Test packets are generated by TG on links to DUTs. TG traffic profile\
| ... | contains two L3 flow-groups (flow-group per direction, 1M 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.
