 * mbuf: The mbuf flags ``PKT_TX_VLAN_PKT`` and ``PKT_TX_QINQ_PKT`` are
   respectively renamed as ``PKT_TX_VLAN`` and ``PKT_TX_QINQ``. The old
   names will be removed in v18.08.

+* 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
+  succesfull. This modification will only impact the PMDs, not the
+  applications.
