The queue index is computed as:\n\n    qid = skb_get_queue_mapping(skb) % ARRAY_SIZE(qdma-\u003eq_tx)\n    txq = netdev_get_tx_queue(dev, qid);\n\nHowever, airoha_qdma_tx_napi_poll() accounts completions across all\nnetdev TX queues (num_tx_queues), leading to inconsistent BQL\naccounting.\n\nAlso reset all netdev TX queues in the ndo_stop callback.",
