Unused queues' napi will not be\nregistered by netif_napi_add(), so the .poll pointer indicates NULL.\nBut it couldn't distinguish whether the napi was unregistered or not\nbecause netif_napi_del() doesn't reset the .poll pointer to NULL.\nSo, ionic_qcq_enable() calls napi_enable() for the queue, which was\nunregistered by netif_napi_del().\n\nReproducer:\n ethtool -L rx 1 tx 1 combined 0\n
