Subject: net: ethtool: Remove PHYLIB direct dependency
Patch-mainline: v5.9-rc1
Git-commit: f3631ab08eeb67ad023ba1b37004ecba0158f93f
References: bsc#1176447
Now that we have introduced ethtool_phy_ops and the PHY library
dynamically registers its operations with that function pointer, we can
remove the direct PHYLIB dependency in favor of using dynamic
operations.

An alternative userspace interface for ethtool based on generic
netlink. It provides better extensibility and some new features,
