+Device Features and Capabilities
+--------------------------------
+
+DMA devices may support different feature sets. The ``rte_dma_info_get`` API
+can be used to get the device info and supported features.
+
+Silent mode is a special device capability which does not require the
+application to invoke dequeue APIs.

* This framework uses 'int16_t dev_id' as the device identifier of a dmadev,
* and 'uint16_t vchan' as the virtual DMA channel identifier in one dmadev.

+ * The functions exported by the dmadev API to setup a device designated by its
+ * device identifier must be invoked in the following order:
+ * - rte_dma_configure()
+ * - rte_dma_vchan_setup()
+ * - rte_dma_start()
+ *
+ * Then, the application can invoke dataplane functions to process jobs.
+ *
+ * If the application wants to change the configuration (i.e. invoke

+ * rte_dma_stop() first to stop the device and then do the reconfiguration
+ * before invoking rte_dma_start() again. The dataplane functions should not
+ * be invoked when the device is stopped.
+ *
+ * Finally, an application can close a dmadev by invoking the rte_dma_close()
+ * function.
+ *
+ * About MT-safe, all the functions of the dmadev API implemented by a PMD are
