I've never looked at the ring/buffer/descriptor structure of the ath9k, but
with most ethernet devices, they would just continue reading descriptors
until it was empty.   Is there some reason that something similar can not
occur?

Or is the problem at a higher level?
Or is that we don't want to enqueue packets so early, because it's a source
of bloat?
