Hello,

I have taken another look also at this text file.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/filesystems/sysfs.txt?id=a6fcdcd94927a1b24dea6a9951ffa7c64545ecfb#n276

The following information is provided at the moment.

…
Top Level Directory Layout
~~~~~~~~~~~~~~~~~~~~~~~~~~

The sysfs directory arrangement exposes the relationship of kernel
data structures.
…
firmware/
net/
fs/
…
TODO: Finish this section.
…


The directory “/sys/net” is not listed on my Linux 5.x system.
Will this documentation get an update?

Regards,
Markus
