39| ... | DUT2. DUT1 and DUT2 tested with ${nic_name}.\
40| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
41| ... | Rate) with zero packet loss tolerance and throughput PDR (Partial Drop\
42| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
43| ... | of packets transmitted. NDR and PDR are discovered for different\
44| ... | Ethernet L2 frame sizes using MLRsearch library.\
45| ... | Test packets are generated by TG on links to DUTs. TG traffic profile\
46| ... | contains two L3 flow-groups (flow-group per direction, up to 64,5k\
47| ... | flows per flow-group) with all packets containing Ethernet header, IEEE\
48| ... | 802.1Q header, IPv4 header with IP protocol=61 and static payload.\
49| ... | MAC addresses are matching MAC addresses of the TG node interfaces.
