| ... | Test packets are generated by TG on links to DUTs. TG traffic profile\
| ... | contains two L3 flow-groups (flow-group per direction, 254 flows\
| ... | per flow-group) with all packets containing Ethernet header, IPv4\
| ... | header with IP protocol=61 and static\ payload. MAC addresses are\
