+One 2n-tx2 testbed is built with: i) one SuperMicro SYS-7049GP-TRT
+server acting as TG and equipped with two Intel Xeon Skylake Platinum
+8180 processors (38.5 MB Cache, 2.50 GHz, 28 cores), and ii) one Marvell
+ThnderX2 9975 (28* ThunderX2) server acting as SUT and equipped with two
+ThunderX2 ARMv8 CN9975 processors. 2n-tx2 physical topology is shown below.
