However, it is not necessary to call netif_napi_del()\nexplicitly, since unregister_netdev() will handle NAPI teardown automatically\nand safely. Removing the redundant call avoids triggering the warning.\n\nFull trace:\n lan78xx 1-1:1.0 enu1: Failed to read register index 0x000000c4. ret = -ENODEV\n lan78xx 1-1:1.0 enu1: Failed to set MAC down
