[PATCH net-next 4/4] net: ethtool: Remove PHYLIB dependency

From: Florian Fainelli
Date: Thu Jul 02 2020 - 00:30:02 EST


Now that we have converted the ethtool/cabletest code to use netdev_ops,
we can remove the PHY library dependency since the function pointers
will now be provided upon PHY attachment to the network device.

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