If the NO_CPU strap is set, the switch starts in 'dumb hub' mode, with all ports enable. Ports which are then actively used are reconfigured as required when the driver starts. However unused ports are left alone. Change this to disable them, and turn off any SERDES interface. This could save some power and so reduce the temperature a bit.

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.
