``_rte_eth_dev_callback_process``. In 17.05 the function will return an ``int``
instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
* ethdev: for 17.05 it is planned to deprecate the following nine rte_eth_dev_*
functions and move them into the ixgbe PMD:
``rte_eth_dev_bypass_init``, ``rte_eth_dev_bypass_state_set``,
``rte_eth_dev_bypass_state_show``, ``rte_eth_dev_bypass_event_store``,
``rte_eth_dev_bypass_event_show``, ``rte_eth_dev_wd_timeout_store``,
``rte_eth_dev_bypass_wd_timeout_show``, ``rte_eth_dev_bypass_ver_show``,
``rte_eth_dev_bypass_wd_reset``.
The following fields will be removed from ``struct eth_dev_ops``:
``bypass_init_t``, ``bypass_state_set_t``, ``bypass_state_show_t``,
``bypass_event_set_t``, ``bypass_event_show_t``, ``bypass_wd_timeout_set_t``,
``bypass_wd_timeout_show_t``, ``bypass_ver_show_t``, ``bypass_wd_reset_t``.
The functions will be renamed to the following, and moved to the ``ixgbe`` PMD:
``rte_pmd_ixgbe_bypass_init``, ``rte_pmd_ixgbe_bypass_state_set``,
``rte_pmd_ixgbe_bypass_state_show``, ``rte_pmd_ixgbe_bypass_event_set``,
``rte_pmd_ixgbe_bypass_event_show``, ``rte_pmd_ixgbe_bypass_wd_timeout_set``,
``rte_pmd_ixgbe_bypass_wd_timeout_show``, ``rte_pmd_ixgbe_bypass_ver_show``,
``rte_pmd_ixgbe_bypass_wd_reset``.
* ABI changes are planned for 17.05 in the ``rte_mbuf`` structure: some fields
may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
``nb_segs`` in one operation, because some platforms have an overhead if the
