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
