+* **Added ethdev desc dump API, to dump Rx/Tx desc info from device.**
+
+Added the ethdev Rx/Tx desc dump API which provides functions for query
+descriptor from device. The descriptor info differs in different NICs.
+The information demonstrates I/O process which is important for debug.
+As the information is different between NICs, the new API is introduced.
+The dump format is vendor-specific.
