The interrupts shouldn't be disabled while receiving skb, but while ctrl_stop, the channels are stopped and all remaining packets are handled with netif_receive_skb(), it can cause WARN_ONCE when ctrl is stopping while not all packets were handled with NAPIs: lock_irq_save cpdma_ctlr_stop cpdma_chan_top __cpdma_chan_free cpsw_rx_handler netif_receive_skb So, split locking while ctrl stop thus interrupts are still enabled while skbs handling. It can cause WARN_ONCE in rare cases when ctrl is stopping while not all packets were handled with NAPIs. Reviewed-by:
