34| ... | *[Cfg] DUT configuration:* DUT1 is configured with two L2 bridge domains

36| ... | Container is connected to VPP via Memif interface. Container is running

38| ... | use cores allocated from pool of isolated CPUs. There are no memory
39| ... | contraints.
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, 254 flows per
47| ... | flow-group) with all packets containing Ethernet header, IPv4 header
48| ... | with IP protocol=61 and static payload. MAC addresses are matching MAC
49| ... | addresses of the TG node interfaces.
