Thanks. Based on that the shaping is done before any of the netfilter
hooks, which is what I was trying to figure out.
On a related note...the deliver_skb() call right before the call to
handle_ing()--is that to allow packet sockets to receive everything that
arrives on the wire even if some of it may be dropped later?
