Downloading MLNX_EN

To download MLNX_EN, perform the following:

1. Verify that the system has a Mellanox network adapter (HCA/NIC) installed.
The following example shows a system with an installed Mellanox HCA:

# lspci -v | grep Mellanox 86:00.0 Network controller [0207]: Mellanox Technologies MT27620 Family Subsystem: Mellanox Technologies Device 0014 86:00.1 Network controller [0207]: Mellanox Technologies MT27620 Family Subsystem: Mellanox Technologies Device 0014 

Note: For ConnectX-5 Socket Direct adapters, use ibdev2netdev to display the installed card and the mapping of logical ports to physical ports. Example:

Notes:

  • Each PCI card of ConnectX-5 Socket Direct has a different PCI address. In the output example above, the first two rows indicate that one card is installed in a PCI slot with PCI Bus address 84 (hexadecimal), and PCI Device Number 00, and PCI Function Number 0 and 1. RoCE assigned mlx5_10 as the logical port, which is the same as netdevice p2p1, and both are mapped to physical port of PCI function 0000:84:00.0.

  • RoCE logical port mlx5_2 of the second PCI card (PCI Bus address 05) and netdevice p5p1 are mapped to physical port of PCI function 0000:05:00.0, which is the same physical port of PCI function 0000:84:00.0.
    MT4119 is the PCI Device ID of the Mellanox ConnectX-5 adapters family.
