We are also considering using the DSW eventdev. Is the DSW designed for such a use case? If so, are there some restrictions and something specific that need to be done to make it work correctly?

The purpose of an event device is to do dynamic load balancing across 
multiple cores. Using the DPDK multiple-process support, with its 
requirement of having unique, non-overlapping, core masks works against 
or even defeats this purpose.

Also, if you care about security, you don't want to disable ASLR.

That said, I can't see any immediate reason why it wouldn't work.
