For the networking subsystem there are two git trees, "net" for bugfixes
and "net-next" for new features, and we specify the target tree using
git send-email --subject-prefix="PATCH net-next".

I assume you would like the v5.12 kernel to actually be functional on
the Ubiquiti ER-X switch, so I would recommend keeping this patch
minimal and splitting it out from the current series, and targeting it
towards the "net" tree, which will eventually get merged into one of the
v5.12 rc's and then into the final version. The other patches won't go
into v5.12 but into v5.13, hence the "next" name.

Also add these lines in your .gitconfig:

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

and run:

git show 3f9ef7785a9c --pretty=fixes
Fixes: 3f9ef7785a9c ("MIPS: ralink: manage low reset lines")

and paste that "Fixes:" line in the commit message, right above your
Signed-off-by: tag.
