I believe this is because the virtual device changes the skb->dev pointer when it xmits, and then pktgen tries to send exactly this pkt again, even though the skb->dev is now hosed up. Unfortunately, my patch will not do the kernel pktgen much good, but next time someone is hacking there, maybe they can fix it :) Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
