When I dump the mbuf's that are being passed to rte_eth_tx_burst() I can confirm that they are in the correct order. However, on the receiving side, tcpdump shows a completely different order. The machines are directly connected to each other using a QSFP cable. Is the reordering of packets inherent to the implementation of DPDK or is there some way I can enforce packets are being send in the order they are provided? Kind regards, Sander
