If those packets came from an another guest, it can block its slots and prevent shutdown. To avoid that, we make sure the queue is drained in every 10 seconds. The QDisc queue in worst case takes 3 round to flush usually. Signed-off-by: Zoltan Kiss Signed-off-by: David S. Miller --- Reading git-diff-tree failed
