I talked to a friend who has already done some DPDK related work.<br>
It seems to be a lot of work with the API and Intel specific parts.<br>
<br>
Since we have some Intel people working on hyperscan, there might<br>
someone with more DPDK background knowledge and how it would fit into<br>
Suricata.<br>
