* cmdline: ``cmdline`` structure will be made opaque to hide platform-specific
content. On Linux and FreeBSD, supported prior to DPDK 20.11,
original structure will be kept until DPDK 21.11.
* raw/ioat: The ``ioat`` rawdev driver has been deprecated, since it's
functionality is provided through the new ``dmadev`` infrastructure.
To continue to use hardware previously supported by the ``ioat`` rawdev driver,
applications should be updated to use the ``dmadev`` library instead,
with the underlying HW-functionality being provided by the ``ioat`` or
``idxd`` dma drivers
