This is good and should be in DPDK documentation along with references
to other Intel/Arm documentation.

I don't see a glossary section in current documentation.
The issue goes deeper there is no clear introduction in the current DPDK documentation.

My suggestion would be something similar to Fd.io VPP and other projects
