-* network includes: Network structures, definitions and functions will
-  be prefixed by ``rte_`` to resolve conflicts with libc headers.
-  This change will break many DPDK APIs.

 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.
 
 * eal: The function ``rte_eal_remote_launch`` will return new error codes
   after read or write error on the pipe, instead of calling ``rte_panic``.
 
-* eal: the ``rte_mem_config`` struct will be made private to remove it from the
-  externally visible ABI and allow it to be updated in the future.

 * eal: both declaring and identifying devices will be streamlined in v18.11.
   New functions will appear to query a specific port from buses, classes of
   device and device drivers. Device declaration will be made coherent with the

   Target release for removal of the legacy API will be defined once most

-* kni: remove KNI ethtool support. To clarify, this is not to remove the KNI,
-  but only to remove ethtool support of it that is disabled by default and
-  can be enabled via ``CONFIG_RTE_KNI_KMOD_ETHTOOL`` config option.
-  Existing KNI ethtool implementation is only supported by ``igb`` & ``ixgbe``
-  drivers, by using a copy of kernel drivers in DPDK. This model cannot be
-  extended to all drivers in DPDK and it is too much effort to maintain
-  kernel modules in DPDK. As a result users won't be able to use ``ethtool``
-  via ``igb`` & ``ixgbe`` anymore.

-* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
-  disable features supported by the crypto device. Only the following features
-  would be allowed to be disabled this way,
-
-  - ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``
-  - ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``
-  - ``RTE_CRYPTODEV_FF_SECURITY``

-  Disabling unused features would facilitate efficient usage of HW/SW offload.

 * cryptodev: the ``uint8_t *data`` member of ``key`` structure in the xforms
   structure (``rte_crypto_cipher_xform``, ``rte_crypto_auth_xform``, and
   ``rte_crypto_aead_xform``) will be changed to ``const uint8_t *data``.

+  In this case the function will return -1 unless the environment is unset first
