[PATCH net-next v2 2/3] net: phy: Register ethtool PHY operations

From: Florian Fainelli
Date: Mon Jul 06 2020 - 00:28:14 EST


Utilize ethtool_set_ethtool_phy_ops to register a suitable set of PHY
ethtool operations in a dynamic fashion such that ethtool will no longer
directy reference PHY library symbols.
