Subject: [net-next RFC PATCH 06/14] net: phy: add support for shared priv data size for PHY package in DT
Add support for defining shared data size for PHY package defined in DT.
A PHY driver has to define the value .phy_package_priv_data_size to make
the generic OF PHY package function alloc priv data in the shared struct
for the PHY package.
