Updating Firmware Using ethtool/devlink and .mfa2 File

In order to flash the firmware on the device using ethtool, you need to prepare a .mfa2 firmware file using the mlxarchive tool - see mlxarchive – Binary Files Compression Tool. Note that mlxarchive requires installing MFT with --oem option.

To perform firmware upgrade using ethtool/devlink, follow the steps below:

1. Run the mlxarchive tool to generate the .mfa2 file (the following example assumes MFA2 v1.1.1).

   Copy

   Copied!

               
   
               
   # mlxarchive -v 1.1.1 --bins-dir <source binaries directory> --out-file /lib/firmware/<file_name>.mfa2
           

2. Obtain the interface name of the adapter for which you wish to update firmware. For example, you can use ifconfig -a.

   # ifconfig -a
   ...
   p5p1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

3. Burn the firmware using the .mfa2 image with ethtool/devlink. Please use the .mfa2 file path relative to /lib/firmware.
   ethtool command:

   # ethtool -f <interface name> <file_name>.mfa2
           

   devlink command:

   $ devlink dev flash <dev> file <file_name>.mfa2
           

4. Query the adapter to verify that the new firmware version has been loaded following.
