   rte_eth_dev_get_sec_ctx() is using uint8_t for port_id, which should be
   uint16_t.
 
+* ethdev: add rx/tx callback functions return named opaque type
+  rte_eth_add_rx_callback(), rte_eth_add_first_rx_callback() and
+  rte_eth_add_tx_callback() functions currently return "void * " but APIs to
+  delete callbacks get "struct rte_eth_rxtx_callback * " as parameter. For
+  consistency functions adding callback will return "struct rte_eth_rxtx_callback * "
+  instead of "void * ".

 * 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
