   Target release for removal of the legacy API will be defined once most
   PMDs have switched to rte_flow.
 
+* 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
+  director APIs. There is no ABI/API break. This change will just remove a
+  global configuration setting and require explicit configuration.
+
 * librte_meter: The API will change to accommodate configuration profiles.
   Most of the API functions will have an additional opaque parameter.
+
+* ring: The alignment constraints on the ring structure will be relaxed
+  to one cache line instead of two, and an empty cache line padding will
+  be added between the producer and consumer structures. The size of the
+  structure and the offset of the fields will remain the same on
+  platforms with 64B cache line, but will change on other platforms.
+
+* mbuf: The control mbuf API (``rte_ctrlmbuf_init()`` function,
+  ``rte_ctrlmbuf_alloc()`` macro, ``rte_ctrlmbuf_free()`` macro,
+  ``rte_ctrlmbuf_data()`` macro, ``rte_ctrlmbuf_len()`` macro,
+  ``rte_is_ctrlmbuf()`` macro and ``CTRL_MBUF_FLAG`` macro) will be
+  removed in v18.05. The packet mbuf API should be used as a
+  replacement.
+
+* 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.
