Subject: [PATCH net-next v3 1/5] ethtool: (uapi) Add ETHTOOL_PHY_GTUNABLE and ETHTOOL_PHY_STUNABLE

From: Raju Lakkaraju <Raju.Lakkaraju@...rosemi.com>

Defines a generic API to get/set phy tunables. The API is using the
existing ethtool_tunable/tunable_type_id types which is already being used
for mac level tunables.
