7 The ``devlink-info`` mechanism enables device drivers to report device
8 (hardware and firmware) information in a standard, extensible fashion.
10 The original motivation for the ``devlink-info`` API was twofold:
12 - making it possible to automate device and firmware management in a fleet
13 of machines in a vendor-independent fashion (see also
14 :ref:`Documentation/networking/devlink/devlink-flash.rst <devlink_flash>`);
15 - name the per component FW versions (as opposed to the crowded ethtool
18 ``devlink-info`` supports reporting multiple types of objects. Reporting driver
19 versions is generally discouraged - here, and via any other Linux API.
