Well, if you are really serious about that, you probably know compat_netmap
exista, and it's functional. You probably know Suricata runs IPS mode under
netmap framework.

http://dpdk.readthedocs.io/en/v16.04/sample_app_ug/netmap_compatibility.html

So a first move in the direction to actually have it running In DPDK
mode with DPDK performance while reusing existing code would be to leverage
on DPDK compat layer with netmap. You wont regret. I personally adjusted a
couple netmap applications to work like that and it saves lota time to find
out the performance difference and investigate if time should be invested
on DPDK when you already have an application running in an other fast
packet processing framework like pf_ring or netmap.

My 2c
