Linux kernel source tree

The rtl8221b and rtl8226b series support switching SerDes mode between 2500base-x and sgmii based on the negotiated copper speed. Configure this switching mode according to SerDes modes supported by host. There is an additional datasheet for RTL8226B/RTL8221B called "SERDES MODE SETTING FLOW APPLICATION NOTE" where a sequence is described to setup interface and rate adapter mode. However, there is no documentation about the meaning of registers and bits, it's literally just magic numbers and pseudo-code.

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 reStructuredText 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.
