I was in doubt when I submitted these, but ended up specfying net-next
instead of net+stable as the target for a reason.  This is a new feature
as Greg says. Even if the feature is essential for your use case, it is
still new. "Has never been supported" isn't really a bug.

And I am still convinced that my decision was correct.  The patches are
a bit more intrusive than I'd be comfortable submitting to stable, as
was demonstrated by the stupid build bug I added... Fixed by commit
5fd99b5d9950 ("net: cdc_ncm: Fix build error") BTW.

This has not been an absolute requirement in the past. Distros tend to
have a more relaxed stable policy.

Using a newer kernel until Debian moves on is obviously also an option.
