I see, for flows in phy-phy setup, they should not be calculate cksum.
I will revise my patch to do the cksum for vhost port only. I will send a
new patch next week.

You're welcome. I forgot to mention my tests were with 64B packets.
For phy-phy the setup
Hi Loftus,
Thanks for testing and the comments!
Can you show more details about your phy-vm-phy,phy-phy setup and testing
steps? Then I can reproduce it to see if I can solve this pps problem.
BTW, how about throughput, did you saw improvment?
I would like to implement vhost->vhost part.
Thanks

Currently, the dpdk-vhost side in ovs doesn't support tcp/udp tx cksum.
So L4 packets's cksum were calculated in VM side but performance is not
good.
Implementing tcp/udp tx cksum in ovs-dpdk side improves throughput and
makes virtio-net frontend-driver support NETIF_F_SG as well
