Mellanox

ConnectX is mlx4 (Ethernet/Infiniband) for ConnectX-3, or mlx5 for ConnectX-4 and above.

Connect-IB is mlx5 (Infiniband only).

Setting Ethernet mode in the firmware

The default link protocol for at least ConnectX-4 is Infiniband. Changing this requires mlxconfig from the MLNX_OFED package's mft deb. mlxconfig requires mft to be running (which requires the mst_pci kernel module); /dev/mst will be populated once this has happened. This device is in Infiniband mode:

[strangelet](0) $ sudo mlxconfig -d /dev/mst/mt4115_pciconf0 query | grep LINK_TYPE
         LINK_TYPE_P1                                IB(1)           
[strangelet](0) $
