Hi Daniel

Thanks for your good catch!
Yes. That's a bug, and it will be fixed in later DPDK releases.

Regards,
Helin

Subject: [dpdk-dev] Loop back mode of the KNI

Hi all,

We're working on the KNI and we see a strange behavior which seems like a bug in the the kernel module.

When running with *lo_mode=lo_mode_fifo *everything works as expected, the packets looks similar on the ingress and egress.
But when running with *lo_mode=lo_mode_fifo_skb *the packets on the egress doesn't include the first 14 bytes (the ethernet header) although the packets size doesn't change.

Thanks,
Daniel
