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:

0000:84:00.0 mlx5_10 (MT4119 - MCX556M-ECAT-S25SN) CX556M - ConnectX-5 QSFP28 fw 16.22.0228 port 1 (DOWN  ) ==> p2p1 (Down)
0000:84:00.1 mlx5_11 (MT4119 - MCX556M-ECAT-S25SN) CX556M - ConnectX-5 QSFP28 fw 16.22.0228 port 1 (DOWN  ) ==> p2p2 (Down)
0000:05:00.0 mlx5_2 (MT4119 - MCX556M-ECAT-S25SN) CX556M - ConnectX-5 QSFP28 fw 16.22.0228 port 1 (DOWN  ) ==> p5p1 (Down)
0000:05:00.1 mlx5_3 (MT4119 - MCX556M-ECAT-S25SN) CX556M - ConnectX-5 QSFP28 fw 16.22.0228 port 1 (DOWN  ) ==> p5p2 (Down)

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.
