1. Introduction of MFT tool
        MFT, is Mellanox/NVIDIA Firmware Tools, is a set of firmware management tools for querying firmware information, firmware upgrades, etc. It contains 4 sub-tools, including mst, mlxburn, flint, and Debug utilities, and the specific functions are referred to the official information of NVIDIA:
table 1 NVIDIA MFT description
      NVIDIA Firmware Tools (MFT)
      The MFT package is a set of firmware management tools used to:
         · Generate a standard or customized NVIDIA firmware image Querying for firmware information
         · Burn a firmware image
       The following is a list of the available tools in MFT, together with a brief description of what each tool performs.
MFT Tools
Tool
Description
    mst
    This tool provides the following functions:
    * Starts/stops the register access driver
    * Lists the available mst devices
    mlxburn
    This tool provides the following functions:
      * Generation of a standard or customized NVIDIA firmware image for burning (in binary or.mlx format)
      * Burning an image to the Flash/EEPROM attached to a NVIDIA HCA or switch device
      * Displaying the VPD (Vital Product Data)of an NVIDIA network adapter
    flint
    This tool burns a firmware binary image or an expansion ROM image to the Flash device of a
        NVIDIA network adapter/gateway/switch device.It includes query functions to the burnt firmware
        image and to the binary image file.
    Debug Utilities
    A set of debug utilities(e.g, itrace, fwtrace, mlxtrace, mlxdump, mstdump, mlxmcg, wqdump, mcra, mlxi2c, i2c,
    mget_temp, and pckt_drop)
2. Download and install MFT tools
Mellanox/NVIDIA official website to download the MFT tool installation package, this article to linux system mft-4.22.1-307-x86_64-rpm.tgz as an example. Installation package download URL: https://network.nvidia.com/products/adapter-software/firmware-tools/
        a. Terminal to decompress the compressed file, execute the command:  tar -zxf mft-4.22.1-307-x86_64-rpm.tgz
        b. Terminal into the decompressed file and install, in order to execute the command:
        cd mft-4.22.1-307-x86_64-rpm
        . /install.sh
        c. Start MFT, run MST, execute the command: mst start
3. MST tool reads the port status and optical module information.
        Execute the command "mlxlink -d device -m " to view the interface information, including interface status, interface configuration, supported rates, troubleshooting, optical module identification, optical module DOM information.
        Note: device is the network address of the interface where the module is located, you can execute the command "lspci" to view.
        The optical module products provided by Moduletek can be used in Mellanox NIC/switch, welcome to purchase.
