+| ... | performance tests for the same DUT confiiguration. Test packets are
+| ... | generated by TG on links to DUTs. TG traffic profile contains two L3
+| ... | flow-groups (flow-group per direction, 100k flows per flow-group) with
+| ... | all packets containing Ethernet header, IPv4 header with IP protocol=61
+| ... | and static payload. Incrementing of IP.dst (IPv4 destination address)
