 * kvargs: The function ``rte_kvargs_process`` will get a new parameter

-* ethdev: Maximum and minimum MTU values vary between hardware devices. In
-  hardware agnostic DPDK applications access to such information would allow
-  a more accurate way of validating and setting supported MTU values on a per
-  device basis rather than using a defined default for all devices. To
-  resolve this, the following members will be added to ``rte_eth_dev_info``.
-  Note: these can be added to fit a hole in the existing structure for amd64
-  but not for 32-bit, as such ABI change will occur as size of the structure
-  will increase.

 * 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.
