+* ethdev: A work is being planned for 18.05 to expose VF port representors
+  as a mean to perform control and data path operation on the different VFs.
+  As VF representor is an ethdev port, new fields are needed in order to map
+  between the VF representor and the VF or the parent PF. Those new fields
+  are to be included in ``rte_eth_dev_info`` struct.
+
+* ethdev: The prototype and the behavior of
+  ``dev_ops->eth_mac_addr_set()`` will change in v18.05. A return code
+  will be added to notify the caller if an error occurred in the PMD. In
+  ``rte_eth_dev_default_mac_addr_set()``, the new default MAC address
+  will be copied in ``dev->data->mac_addrs[0]`` only if the operation is
+  successful. This modification will only impact the PMDs, not the
+  applications.

 * i40e: The default flexible payload configuration which extracts the first 16
   bytes of the payload for RSS will be deprecated starting from 18.02. If
   required the previous behavior can be configured using existing flow
