Yeah, fair enough. It's not the end of the world having it in a separate
word. I was just trying to avoid bloating the structure more than we
needed to.

Acked-by: David Woodhouse <David.Woodhouse@...el.com> for your new
version of patch #6 (returning DROP_PACKET for !VF_READY), and your
followup to my patch #8, adding the 'need_wakeup' flag. Which we might
as well merge into (the pppoatm part of) my patch.

Chas, are you happy with the generic ATM part of that? And the
nomenclature? I didn't want to call it 'release_cb' like the core socket
code does, because we use 'release' to mean something different in ATM.
So I called it 'unlock_cb' instead...
