Subject: [PATCH 011/146] iwlwifi: mvm: wait for the flushed queue only
Git-commit: 0b90964a265d6e0b60182b88f3947c6ef0ae4184
Patch-mainline: v4.13-rc1
References: FATE#322675
The function flushed only agg queue and no more traffic
is queued on it.
However, it waits for all queues to empty, which is not
necessary and may take more time.
