-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
-
-- Set CQE COMPRESSION to "AGGRESSIVE":
- ::
-
- $ mlxconfig -d $PORT_PCI_ADDRESS set CQE_COMPRESSION=1
-
-Mellanox :abbr:`OFED (OpenFabrics Enterprise Distribution)` driver is installed
-and used to manage the NIC settings.
