From 9994338227179eaf8db6f4493504e108b1fae5fc Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 25 Apr 2018 12:12:48 -0700 Subject: net: Allow network devices to have PHY statistics Add a new callback: get_ethtool_phy_stats() which allows network device drivers not making use of the PHY library to return PHY statistics. Update ethtool_get_phy_stats(), __ethtool_get_sset_count() and __ethtool_get_strings() accordingly to interogate the network device about ETH_SS_PHY_STATS.
