parentr8169: add helper r8168g_phy_param (diff)

r8169: add helper r8168d_phy_param
Integrated PHY's from RTL8168d support an indirect access method for PHY parameters. On page 0x0005 parameter number is written to register 0x05, then the parameter can be accessed via register 0x06. Add a helper for this to improve readability and simplify the code. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
