 To perform data copies using IOAT dmadev devices, the functions

+To retrieve information about completed copies, the API
+``rte_dma_completed()`` or  ``rte_dma_completed_status ()``should be used.
+``rte_dma_completed()`` will return to the application how many operations
+have successfully completed up to a supplied maximum, it can also pass back the
+index of the last completed operation and if a completion within the requested
+batch has failed. If ``rte_dma_completed()`` passes back ``has_error`` as
+``true`` then ``rte_dma_completed_status()`` should be called to retrieve
+the detailed status of each completion in that batch. Once an error has occurred
+``rte_dma_completed()`` will not process any more completions until
+``rte_dma_completed_status()`` has been called to get the error information.
+The supplied ``status`` array will contain either ``RTE_DMA_STATUS_SUCCESSFUL``
+if the operation was successful or a DMA error code if the operation failed.
+The status codes supported by IOAT are:
+
+* ``RTE_DMA_STATUS_SUCCESSFUL``: The operation was successful.
+* ``RTE_DMA_STATUS_INVALID_SRC_ADDR``: The operation failed due to an invalid source address.
+* ``RTE_DMA_STATUS_INVALID_DST_ADDR``: The operation failed due to an invalid destination address.
+* ``RTE_DMA_STATUS_INVALID_LENGTH``: The operation failed due to an invalid descriptor length.
+* ``RTE_DMA_STATUS_DESCRIPTOR_READ_ERROR``: The device could not read the descriptor.
+* ``RTE_DMA_STATUS_ERROR_UNKNOWN``: The operation failed due to an unspecified error.
+
+``rte_dma_completed_status()`` can be used on it's own instead of with
+``rte_dma_completed()`` but calling ``rte_dma_completed_status()`` may be
+slower than ``rte_dma_completed()``.
+
+The following code shows how to retrieve the number of successfully completed
+copies within a burst and then using ``rte_dma_completed_status()`` to check
+which operation failed and reset the device:
+
+.. code-block:: C
+
+   enum rte_dma_status_code status[COMP_BURST_SZ];
+   uint16_t count, idx, status_count;
+   bool error = 0;
+
+   count = rte_dma_completed(dev_id, vchan, COMP_BURST_SZ, &idx, &error);
+
+   if (error){
+      status_count = rte_dma_completed_status(dev_id, vchan, COMP_BURST_SZ, &idx, status);
+   }
+
+After this snippet the application would use the status array to find which copy
+failed and handle it appropriately.
