dwc_eth_qos: Remove deprecated create_singlethread_workqueue
alloc_workqueue replaces deprecated create_singlethread_workqueue(). A dedicated workqueue has been used since the workitem viz lp->txtimeout_reinit is involved in reinitialization if a TX timeout occurs, which is necessary to guarantee forward progress in packet processing. As a network device can be used during memory reclaim, the workqueue needs forward progress guarantee under memory pressure. WQ_MEM_RECLAIM has been set to ensure this. Since there is only a single work item, explicit concurrency limit is unnecessary here. Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: David S.
