Yes, some IP forwarding of 60 byte frames at line rate gigabit or higher should do the trick. Testing with MTU sized packets is probably not going to show much of a difference.Well, I don't see much of a difference. However, running iperf3 with small packets is nowhere near line rate of 100Mbit/s.
Try something smarter than iperf3, like CONFIG_NET_PKTGEN=y on a link partner as traffic generator. I had this command lying around, I forget exactly what it does. /root/git/net-next/samples/pktgen/pktgen_sample03_burst_single_flow.sh \ -i eth1 -s 64 -m 00:04:9f:05:de:0a -d 20.0.0.2 -t 2 -f 13 -c 4 -p 400 -n 0 -b 4
