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 5th generation devices, it is also possible to query the default configurations and the configurations that are used by the current running firmware.
