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

 ABI Changes
 -----------
 
+* The ethdev ``rte_eth_link`` and ``rte_eth_conf`` structures were changed to

+
+* The ethdev ``rte_eth_dev_info`` was changed to support device speed

   the previous releases and made in this release. Use fixed width quotes for
   ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
