====================
net: phy: realtek: add support for integrated 2.5Gbps PHY in RTL8125

This series adds support for the integrated 2.5Gbps PHY in RTL8125.
First three patches add necessary functionality to phylib.

Changes in v2:
- added patch 1
- changed patch 4 to use a fake PHY ID that is injected by the
  network driver. This allows to use a dedicated PHY driver.
