   has exposed, like the way we have done with uio-pci-generic. This change
   targets release 17.02.
 
+* ABI/API changes are planned for 17.02: ``rte_device``, ``rte_driver`` will be
+  impacted because of introduction of a new ``rte_bus`` hierarchy. This would
+  also impact the way devices are identified by EAL. A bus-device-driver model
+  will be introduced providing a hierarchical view of devices.
+
+* ``eth_driver`` is planned to be removed in 17.02. This currently serves as
+  a placeholder for PMDs to register themselves. Changes for ``rte_bus`` will
+  provide a way to handle device initialization currently being done in
+  ``eth_driver``.
+
 * In 17.02 ABI changes are planned: the ``rte_eth_dev`` structure will be
   extended with new function pointer ``tx_pkt_prepare`` allowing verification
   and processing of packet burst to meet HW specific requirements before
