This adds support for the integrated 2.5Gbps PHY in Realtek RTL8125. Advertisement of 2.5Gbps mode is done via a vendor-specific register. Same applies to reading NBase-T link partner advertisement. Unfortunately this 2.5Gbps PHY shares the PHY ID with the integrated 1Gbps PHY's in other Realtek network chips and so far no method is known to differentiate them. As a workaround use a dedicated fake PHY ID that is set by the network driver by intercepting the MDIO PHY ID read. v2: - Create dedicated PHY driver and use a fake PHY ID that is injected by the network driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
