Unfortunately it seems so :( The patches got marked as Not Applicable
in patchwork. And now we are once again in the merge window period.
Please repost late next week, and make sure to prefix the subjects with
[PATCH net-next v12], this will hopefully prevent mis-categorization.

Looking at the code again is the use of netif_stop_queue(ndev) in
ax88796c_close() not a little racy? The work may be running in parallel 
and immediately re-enable the queue.
