How does this compare with the "nnpi" driver being proposed here:
	https://lore.kernel.org/r/20210513085725.45528-1-guy.zadicario@intel.com

Please work with those developers to share code and userspace api and
tools.  Having the community review two totally different apis and
drivers for the same type of functionality from the same company is
totally wasteful of our time and energy.
