| ... | at line rate and reports total received/sent packets over trial period.
| ... | Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, one flow per flow-group) with all packets
| ... | containing Ethernet header, IPv4 header with UDP header and static
| ... | payload. MAC addresses are matching MAC addresses of the TG node
