Should the ip fragmentation table be single received by a single rx-queue? Because I am not sure whether I will receive all the fragmented messages correctly when I try to receive and combine the packets using multiple rx-queues with multiple logical cores. I have currently build an example that only uses one rx-queue with multiple tx-queues and assemble the fragmented messages with a single frag-table. But I am not sure how to scale this..
