From c59530d0d5dccc96795af12c139f618182cf98db Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 25 Apr 2018 12:12:47 -0700 Subject: net: Move PHY statistics code into PHY library helpers In order to make it possible for network device drivers that do not necessarily have a phy_device attached, but still report PHY statistics, have a preliminary refactoring consisting in creating helper functions that encapsulate the PHY device driver knowledge within PHYLIB.
