From a6cd0d2d493ab7806b49f738b4f66362437cc09e Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 27 May 2019 19:06:38 -0700 Subject: [PATCH] Documentation: net-sysfs: Remove duplicate PHY device documentation Both sysfs-bus-mdio and sysfs-class-net-phydev contain the same duplication information. There is not currently any MDIO bus specific attribute, but there are PHY device (struct phy_device) specific attributes. Use the more precise description from sysfs-bus-mdio and carry that over to sysfs-class-net-phydev.
