Thanks for the suggestion.

UADK is a framework for user application to access hardware accelerator .
https://github.com/Linaro/uadk/blob/master/docs/wd_design.md
UADK relies on SVA (Shared Virtual Address) that needs to be supported
by IOMMU.
As a result, user application can directly use virtual address for dma,
since iommu and
mmu share the same virtual address by coping the same page table, which
enhance the
performance as well as easy usability.
UADK provide algorithm libraries and api for application to use.
The library will find the real hardware in the platform.
We also provide openssl engine for uadk,
https://github.com/Linaro/uadk_engine
For alignment, we planned to provide uadk dpdk pmd as well, with the
name as UADK.
What do you think.
Thanks.
