> alloc_workqueue replaces deprecated create_singlethread_workqueue().
> A dedicated workqueue has been used since the workitems are being used
> on a packet tx/rx path. Hence, WQ_MEM_RECLAIM has been set to guarantee
> forward progress under memory pressure.
> An ordered workqueue has been used since workitems &cfhsi->wake_up_work
> and &cfhsi->wake_down_work cannot be run concurrently.
> Calls to flush_workqueue() before destroy_workqueue() have been dropped
> since destroy_workqueue() itself calls drain_workqueue() which flushes
> repeatedly till the workqueue becomes empty.
