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 queue before URB is done\n}\n\nkaweth_start_xmit() {\n    netif_stop_queue();\n    usb_submit_urb(kaweth->tx_urb); // URB submitted while active\n}\n\nThis triggers the WARN in usb_submit_urb():\n\n  \"URB submitted while active\"\n\nThis is a similar class of bug fixed in rtl8150 by\n\n- commit 958baf5eaee3 (\"net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast\").\n\nAlso kaweth_set_rx_mode() is already functionally broken, the\nreal set_rx_mode action is performed by kaweth_async_set_rx_mode(),\nwhich in turn is not a no-op only at ndo_open() time.","state":0,"publishedAt":"2026-05-06T11:27:52.983+00:00","modifiedAt":"2026-10-19T19:16:22.908+00:00","affected":[{"ecosystem":"Vendor
