We need to see the use case for any new hook.

I'm afraid we've seen way too many cases of new hooks added to the
kernel tree only to never see their corresponding implementations
come along, so now there's a requirement to post an implementation
along with a hook.

Also, please review the netdev FAQ, if you can find it... I can't
anymore. It'll tell you how to submit patches, when to submit them,
how to indicate which tree, etc.

You can find the source file for what I think _was_ the FAQ at:

Documentation/process/maintainer-netdev.rst

but this doesn't seem to be in the documentation tree on kernel.org
(or at least is not in an obvious place.)
