traffic-mirrorer/redirector is a type of netfilter that just
mirror/redirect packets between netdev and chardev (just the mirror
client/sever and redirect client/sever in the above graph)
colo-rewriter is a type of netfilter that did ack/seq adjust (just the
TCP rewriter in the above graph)
colo-comparer is a thread object that did packet comparing (similar to
"compare" in the above graph but not a netfiler)
