[dpdk-dev] [PATCH v4 00/25] raw/ioat: enhancements and new hardware support

This patchset adds some small enhancements, some rework and also support
for new hardware to the ioat rawdev driver. Most rework and enhancements
are largely self-explanatory from the individual patches.

The new hardware support is for the Intel(R) DSA accelerator which will be
present in future Intel processors. A description of this new hardware is
covered in [1]. Functions specific to the new hardware use the "idxd"
prefix, for consistency with the kernel driver.

 * Fixed compile with FreeBSD clang
 * Improved autotests for fill operation

 * More doc updates including release note updates throughout the set
 * Added in fill operation
 * Added in fix for missing close operation
 * Added in fix for doc building to ensure ioat is in in the index

 * Included documentation additions in the set
 * Split off the rawdev unit test changes to a separate patchset for easier
 * General code improvements and cleanups
