-| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for IPv4 routing.
-| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with IPv4
-| ... | routing and two static IPv4 /24 route entries. Qemu Guest is connected
-| ... | to VPP via vhost-user interfaces. Guest is running DPDK testpmd
-| ... | interconnecting vhost-user interfaces using 5 cores pinned to cpus 5-9
-| ... | and 2048M memory. Testpmd is using socket-mem=1024M (512x2M hugepages),

-| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
-| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
-| ... | of packets transmitted. NDR and PDR are discovered for different
-| ... | 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
-| ... | interfaces.
-| ... | *[Ref] Applicable standard specifications:* RFC2544.
