There will always be a need for a "stop all the TX queues" operation.

The question is if the current way is "all correct". As a matter of
fact I think Peter's doubts could be justified: taking "USHORT_MAX"
locks looks really dubious (so maybe it's not so strange lockdep
didn't get used to this).

There are, of course, potentially other ways to achieve the objective.

And for non-multiqueue aware devices (which is the vast majority of
the 400 or so networking drivers we have) there is only one queue and
thus one lock taken.
