mlx5 devlink support¶

This document describes the devlink features implemented by the mlx5 device driver.

Parameters¶

Generic parameters implemented¶
Name Mode
enable_roce driverinit

The mlx5 driver also implements the following driver-specific parameters.

Driver-specific parameters implemented¶
Name Type Mode Description
flow_steering_mode string runtime

Controls the flow steering mode of the driver

  • dmfs Device managed flow steering. In DMFS mode, the HW steering entities are created and managed through firmware.
  • smfs Software managed flow steering. In SMFS mode, the HW steering entities are created and manage through the driver without firmware intervention.

The mlx5 driver supports reloading via DEVLINK_CMD_RELOAD

Info versions¶

The mlx5 driver reports the following versions

devlink info versions implemented¶
Name Type Description
fw.psid fixed Used to represent the board id of the device.
fw.version stored, running Three digit major.minor.subminor firmware version number.
