 New Features
 ------------
 
+* **ethdev: define a set of advertised link speeds.**
+
+  Allowing to define a set of advertised speeds for auto-negociation,
+  explicitely disable link auto-negociation (single speed) and full
+  auto-negociation.
+
+* **ethdev: add speed_cap bitmap to recover eth device link speed capabilities
+  define a set of advertised link speeds.**
+
+  ``struct rte_eth_dev_info`` has now speed_cap bitmap, which allows the
+  application to recover the supported speeds for that ethernet device.
 
 Resolved Issues

   Fixed issue where an incorrect Cuckoo Hash key table size could be
