34| ... | *[Top] Network Topologies:* TG-DUT1-TG 2-node circular topology\

39| ... | *[Cfg] DUT configuration:* DUT1 is configured with L2 bridge-\
40| ... | domain and MAC learning enabled. Qemu VNFs are connected\
41| ... | to VPP via vhost-user interfaces. Guest is running testpmd l2xc\
42| ... | interconnecting vhost-user interfaces, rxd/txd=1024. DUT1 is\
43| ... | tested with ${nic_name}.
44| ... | *[Ver] TG verification:* TG finds and throughput NDR (Non Drop\
45| ... | Rate) with zero packet loss tolerance, then measured loss at this load\
46| ... | while additional chain is configured.\
47| ... | Test packets are generated by TG on links to DUTs. TG traffic profile\
48| ... | contains two L3 flow-groups (flow-group per direction, 256 flows per\
49| ... | flow-group) with all packets containing Ethernet header with .1Q, IPv4\
50| ... | header, UPD header, VXLAN header and static payload. MAC addresses are\
51| ... | matching MAC addresses of the TG node interfaces.
52| ... | *[Ref] Applicable standard specifications:* RFC2544, RFC7348.
