The Marvell 88E6060 uses tag_trailer.c and the KSZ8795, KSZ9477 and
KSZ9893 switches also use tail tags.

thanks for pointing out how to use this feature. I did this manually up to now.

I added it manually because the commit ID is not from Linus' tree. Is there any
value using Fixes tags with id's from other trees?

Yes, that's what "git merge" does, it keeps sha1sums.
You should check out "git log --oneline --graph --decorate" some time.
Every maintainer's history is linear, and so is Linus's.

One thing to add is that we never rebase net or net-next trees
(some maintainers would do that occasionally).
Applied, thanks everyone!
