   The format of device command line parameters will change. The bus will need
   to be explicitly stated in the device declaration. The enum ``rte_devtype``
   was used to identify a bus and will disappear.
   The structure ``rte_devargs`` will change.
   The ``rte_devargs_list`` will be made private.

-* ethdev: Tx offloads will no longer be enabled by default in 17.11.
-  Instead, the ``rte_eth_txmode`` structure will be extended with
-  bit field to enable each Tx offload.
-  Besides of making the Rx/Tx configuration API more consistent for the
-  application, PMDs will be able to provide a better out of the box performance.
-  As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.
+* ethdev: a new Tx and Rx offload API was introduced on 17.11.
+  In the new API, offloads are divided into per-port and per-queue offloads.
+  Offloads are disabled by default and enabled per application request.
+  The old offloads API is target to be deprecated on 18.05. This includes:
+
+  - removal of ``ETH_TXQ_FLAGS_NO*`` flags.
+  - removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
+  - removal of the offloads bit-field from ``rte_eth_rxmode`` struct.
