Register this callback function in your EVT_NET_ADAPTER_CREATE_TX(RX)QUEUE callback. Set the appropriate member of a NET_PACKET_QUEUE_CONFIG structure when you are initializing the structure with NET_PACKET_QUEUE_CONFIG_INIT, then call NetTx(Rx)QueueCreate.
NetAdapterCx serializes this callback function along with the packet queue's EVT_PACKET_QUEUE_CANCEL and EVT_PACKET_QUEUE_SET_NOTIFICATION_ENABLED callback functions.
For more info and a diagram showing the NetAdapterCx data path polling model, see Transmit and receive queues. For more info about ring buffer usage, see Using the ring buffer.
For an example of implementing this callback for a transmit queue, see Sending network data with net rings. For an example of implementing this callback for a receive queue, see Receiving network data with net rings.
