Subject: [PATCH v2 net-next 4/8] r8169: Modify the method for setting firmware
Remove useless action PHY_READ_EFUSE, PHY_READ_MAC_BYTE, PHY_WRITE_MAC_BYTE,
PHY_WRITE_ERI_WORD. And define the new action PHY_MDIO_CHG.
PHY_MDIO_CHG is used to modify the mdio operation. By the way, the
firmware could support setting mac ocp.
