Note that this is only for the 4.4 branch as the regression is only in
they have been destroyed but before they have been recreated. Extend the
region covered by the rtnl semaphore to protect against this race. There
is a possibility that we fail to recreate the queues so check for this
in the open function.

before it has set up the queues and is actually usable. A userspace too

I've now added CC'd netdev on the other two.
That doesn't work.
If you don't post the originals explicitly to netdev then it won't
get properly

xps_needed is incremented only when a new dev map is allocated (in

actually have a dev map to destroy. Without

out of sync and eventually the above-mentioned crash would occur.
