These are TX queue flow\ncontrol functions unrelated to RX multicast configuration.\n\nThe premature netif_wake_queue() can re-enable TX while tx_urb is still\nin-flight, leading to a double usb_submit_urb() on the same URB:\n\nkaweth_start_xmit() {\n netif_stop_queue();\n usb_submit_urb(kaweth->tx_urb);\n}\n\nkaweth_set_rx_mode() {\n netif_stop_queue();\n netif_wake_queue(); // wakes TX
