1. Use info from DT if available It allows describing for example a fixed link. It's more accurate than just guessing there may be one (depending on a chipset). 2. Verify PHY ID before trying to connect PHY PHY addr 0x1e (30) is special in Broadcom routers and means a switch connected as MDIO devices instead of a real PHY. Don't try connecting to it.

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.
