| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-
| ... | domain and MAC learning enabled. Qemu Guest is connected to VPP via
| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting
| ... | vhost-user interfaces using 3 cores pinned to cpus 5,6,7 and 2048M
| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 3 cores
| ... | (1 main core and 2 cores dedicated for io), forwarding mode is set to

| ... | Ethernet L2 frame sizes using either binary search or linear search
| ... | algorithms with configured starting rate and final step that determines
| ... | throughput measurement resolution. Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, 253 flows per flow-group) with all packets
| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
| ... | payload. MAC addresses are matching MAC addresses of the TG node
