Why the fact that I replied to that original thread with the message
below is being ignored?

"Just notice that the idea behind this and the following patch is exactly
the same:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next.git/commit/?id=3f95e92c8a8516b745594049dfccc8c5f8895eea

I could resend this same patch with a different changelog text, but I
don't think such a thing is necessary. However, if people prefer that
approach, just let me know and I can do it.

Thanks

Gustavo"

Why no one replied to what I was proposing at the time?

It seems to me that the person that was ignored was actually me, and not the
other way around. :/
