+Mellanox NIC
+------------
+
+Performance test results using Mellanox ConnectX5 2p100GE are reported for
+2-Node Xeon Cascade Lake physical testbed type present in FD.io labs. For
+description of physical testbeds used please refer to
+:ref:`tested_physical_topologies`.
+
+Mellanox NIC settings
+~~~~~~~~~~~~~~~~~~~~~
+
+Mellanox ConnectX5 NIC settings are following recommendations from
+[DpdkPerformanceReport]_, [MellanoxDpdkGuide]_ and [MellanoxDpdkBits]_.
+Specifically:
+
+- Flow Control OFF:
+ ::
+
+ $ ethtool -A $netdev rx off tx off
+
+- Change PCI MaxReadReq to 1024B for each port of each NIC:
+ ::
+
+ $ setpci -s $PORT_PCI_ADDRESS 68.w=3BCD
+
+- Set CQE COMPRESSION to "AGGRESSIVE":
+ ::
+
+ $ mlxconfig -d $PORT_PCI_ADDRESS set CQE_COMPRESSION=1
+
+Mellanox :abbr:`OFED (OpenFabrics Enterprise Distribution)` driver of version
+4.6-1.0.1.1 is installed and used to manage the NIC settings.
