Hi Salil You don't really have a user api using debugfs, because debugfs is unstable. Anything can change at any time. Any user tools which use debugfs can be expected to break at any time as the information in debugfs changes. debugfs is for debug, not to export an API. And in production systems, it is often not mounted. As much as possible, you are recommended to use existing APIs, ethtool, devlink, etc. Andrew
