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
