Subject: [net-next v3 7/8] i40e: sysfs and debugfs interfaces
From: Jesse Brandeburg <jesse.brandeburg@...el.com>
This driver includes a debugfs interface for developers to get more hardware
information in real-time.
This patch also includes a sysfs interface for root users to use to help
configure/view some of the internal parameters of the device.
