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.

V6:
* Add explicit __rte_experimental tag on all functions.
[Previously header just had note saying all contents are experimental]
V5:
* Rebased to latest main branch.
V4:
* Fixed compile with FreeBSD clang
* Improved autotests for fill operation
V3:
* 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
V2:
* Included documentation additions in the set
* Split off the rawdev unit test changes to a separate patchset for easier
review
* General code improvements and cleanups
