net: phy: realtek: add support for RTL8211C
RTL8211C has an issue when operating in Gigabit slave mode, therefore genphy driver can't be used. See also this U-boot change. https://lists.denx.de/pipermail/u-boot/2016-March/249712.html Add a PHY driver for this chip with the quirk to force Gigabit master mode. As a note: This will make it impossible to connect two network ports directly which both are driven by a RTl8211C. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
