- * Description: vnt_tx_context_complete
- *     1a) Indicate to the protocol the status of the write.
- *     1b) Return ownership of the packet to the protocol.
- *
- *     2)  If any more packets are queue for sending, send another packet
- *         to USBD.

- * Parameters:
- *  In:

- *                      completed the irp
- *      pIrp          - the irp which was completed by the

- *                      before calling IoCallDriver on the irp
- *                      The pContext is a pointer to the USB device object.
- *  Out:

- *
- * Return Value: STATUS_MORE_PROCESSING_REQUIRED - allows the completion routine
- *               (IofCompleteRequest) to stop working on the irp.
