r8169: add support for RTL8116af

Browse source

RTL8116af is sfp mode. Phylink uses pcs to get the link status from its
serdes reg, instead of standard phy reg. Speed and duplex are hardcoded
to 1000Mbps Full-Duplex. Also, RTL8116af doesn't have internal phy, so
we add some checks to ensure that tp->phydev is not empty when we need it.
In rtl_hw_start_8117(), the MAC calibration for register 0xd412 relies
on reading the internal PHY register 0x0c42. Since RTL8116af does not
have an internal PHY, this calibration step is intentionally bypassed.
