of the RSS implementation and described in detail the issues with properly load-balancing fragmented IP traffic.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Would it be possible to add a new ‘trivial’ load balancer (e.g. cluster_peer) that ignores the hash from the kernel and just load balances on the IP header src->dst?
There is still the issue that the fragments may be delivered out-of-order to the worker threads, but I think suricata can handle that?<o:p></o:p></span></p>

<p class="MsoNormal">How about ignoring layers above 3 and just going with ip src + ip dst? I'm pretty sure I can do that on i40e.<o:p></o:p></p>
