Yes, but what I am interested in at this moment is to how to utilize
similar techniques for optimizing large iptables rulesets. My routing
tables rarely contain more than a handful of rules even in the most
The tc code is quite different from the iptables code.
The actual act of the method of selecting which chain to jump to is
not a big deal, the question is more of how to make iptables make the
actual jump in the best manner, and how to build the argument list to
the jump target in a manner that makes sense to the userspace
