Please *always* explain WHY this patch is needed.
When reading the code, it is not clear to me what you are trying to fix
here: with the Netlink PM, the userspace adds and deletes endpoints, not
specific subflows. I mean: we don't have the same issue as we have with
the userspace PM. Or is there a different issue?
Cheers,
Matt
