The idea is perfect but the commit isn't.

First of all, put this in your .gitconfig.

[core]
	abbrev = 12
[pretty]
	fixes = Fixes: %h (\"%s\")

Now if you run
"git show 7a6ffe764be35af0527d8cfd047945e8f8797ddf --pretty=fixes",
you'll see:

Fixes: 7a6ffe764be3 ("net: dsa: point out the tail taggers")

Notice how there's no [net] tag?
People complain when the format of the Fixes: tag is not standardized.

Secondly, can you please come up with a commit description that is
_different_ from the commit you're fixing? As a backporter I would hate
to have 2 commits with the same title, I would surely mess them up.

How about:
net: dsa: tag_ksz: KSZ8795 and KSZ9477 also use tail tags
