[dpdk-dev] [PATCH 20.11 00/20] raw/ioat: enhancements and new hardware support

[Bruce Richardson]

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.

This set is being sent for initial review and evaluation. Any documentation
changes needed and a few additional updates to the code are planned for V2
of this patchset in the 20.11 timeframe.
