Describe the Distributed Switch Architecture (DSA) - compliant

Why is this document part of Linux code base ?

It's fine, but your are right with your latter questions.

How will the other OSes be aware of this ?

Should be a standard somewhere.

I assume there was some repository to maintain such DSDs so that it
is accessible for other OSes. I am not agreeing or disagreeing on the
change itself, but I am concerned about this present in the kernel
code.

I dunno we have a such, but the closest I may imagine is MIPI standardization,
that we have at least for cameras and sound.

I would suggest to go and work with MIPI for network / DSA / etc area, so
everybody else will be aware of the standard.
