+| Documentation |  *Raw results L2XC test cases*

+| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology
+| ... | with single links between nodes.
+| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 cross connect.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 configured with L2 cross-
+| ... | connect. DUT1 and DUT2 tested with 2p10GE NIC X710 by Intel.
+| ... | Container is connected to VPP via Memif interface running same VPP
+| ... | version as running on DUT. Resources are limited via cgroup to use 5
+| ... | cores allocated from pool of isolated CPUs. There are no memory
+| ... | contraints. Cross Horizontal topology with packets flowing via DUT (VPP)
+| ... | to Container, then via horizontal memif to the next Container, and so on
+| ... | until the last Container then to NIC (in last Container). Single
+| ... | Container is supported as of now.
+| ... | *[Ver] TG verification:* In MaxReceivedRate test TG sends traffic
+| ... | at line rate and reports total received/sent packets over trial period.
+| ... | Test packets are generated by TG on links to DUTs. TG traffic profile
+| ... | contains two L3 flow-groups (flow-group per direction, 254 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.
