Subject: [Intel-wired-lan] [PATCH iwl-next v5 06/13] idpf: remove SW marker
handling from NAPI

From: Michal Kubiak <redacted>

SW marker descriptors on completion queues are used only when a queue is
about to be destroyed. It's far from hotpath and handling it in the hotpath
NAPI poll makes no sense.
Instead, run a simple poller after a virtchnl message for destroying the queue
is sent and wait for the replies. If replies for all of the queues are received,
this means the synchronization is done correctly and we can go forth with
stopping the link.
