This patch replaces the usage of netif_stop_queue with netif_device_detach in the u_ether driver. The netif_device_detach function not only stops all tx queues by calling netif_tx_stop_all_queues but also marks the device as removed by clearing the __LINK_STATE_PRESENT bit. This change helps notify user space about the disconnection of the device more effectively, compared to netif_stop_queue, which only stops a single transmit queue.
