Those two were broken out so that the same primary yaml could be shared across hosts with the same hardware.<o:p></o:p></p>

I've seen similar errs in a couple of situations:<br>
1 - when there is another Suricata running on the same interface<br>
2 - when using XDP (hw mode) with the wrong/not correct firmware<br>
version of the NIC<br>
<br>
From what I gather , it seems you don't have any the situation above<br>
(if I am not mistaken)<br>
Off note: For the cluster_qm part it is known that i40 can do the<br>
symmetric hashing with the specified low entropy key for ixgbe i am<br>
not sure as i've seen both expected and unexpected results so ti is<br>
something that needs to be further checked.<br>
However there is a bit more to that even if set up correct - it is<br>
traffic dependent in some cases as well - it's been tracked here<br>

I dont have that much experience with CentOS but will be curious to<br>
see if you have similar issue with CentOS 8<br>
