I would like to downgrade this patch from tag net-next to RFC.

After Dave Taht talked to me, I realized that this change could have drastic
impact on how packets could starve in various qdiscs if a router is last hop
for a ping scan.

Please postpone this patch until I did more research. Comments are welcome,
too.

Thanks,

  Hannes
