| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores
| ... | (1 main core and 4 cores dedicated for io), forwarding mode is set to
| ... | io, rxd/txd=256, burst=64. Scheduler policy is set to SCHED_RR with

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