====================
r8169: add support for RTL8125

This series adds support for the 2.5Gbps chip RTl8125. It can be found
on PCIe network cards, and on an increasing number of consumer gaming
mainboards. Series is partially based on the r8125 vendor driver.
Tested with a Delock 89531 PCIe card against a Netgear GS110MX
Multi-Gig switch.
Firmware isn't strictly needed, but on some systems there may be
compatibility issues w/o firmware. Firmware has been submitted to
linux-firmware.

v2:
- split first patch into 6 smaller ones to facilitate bisecting
