| ... | performance tests for the same DUT configuration. Test packets are

| ... | flow-groups (flow-group per direction, 254 flows per flow-group) with
| ... | all packets containing Ethernet header, IPv4 header with IP protocol=61
| ... | and generated payload. MAC addresses are matching MAC addresses of the
