To change the networking high-speed ports mode, you can either use the mlnxconfig or UEFI tools.

UEFI can be used to configure the adapter card device before the operating system is up

while mlnxconfig can be used once the operating system is up.

According to your preference, use one of the below tools:

The mlxconfig tool allows the user to change some of the device configurations without reburning

the firmware. The configuration is also kept after reset. By default, mlxconfig shows the

configurations that will be loaded in the next boot. For more information and instructions, refer

to mlnxconfig.

PreBoot drivers first initialize the adapter device, senses the port protocol – Ethernet or InfiniBand,

and brings up the port. Then it connects to a DHCP server to obtain its assigned IP address and

network parameters, and also to obtain the source location of the kernel/OS to boot from. The

DHCP server instructs the PreBoot drivers to access the kernel/OS through a TFTP server, an iSCSI

target, or some other service. For more information and instructions, refer to UEFI.
