probable bug in pktgen

While testing my own pktgen code I noticed that I can cause spectacular crashes by setting the 'multiskb' to > 1 and using VLAN interfaces. 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 :)
