From 4895d7808e7030c831f2ef83a3cc6ec0d46c30b1 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Sun, 5 Jul 2020 21:27:56 -0700 Subject: net: ethtool: Introduce ethtool_phy_ops In order to decouple ethtool from its PHY library dependency, define an ethtool_phy_ops singleton which can be overriden by the PHY library when it loads with an appropriate set of function pointers.
