[v2,00/18] 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. *** SUBJECT HERE ***

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

Forgot to add that this patchset is based on top of the proposed rawdev API
