This option adds a new iptables `hashlimit' match.
As opposed to `limit', this match dynamically crates a hash table
of limit buckets, based on your selection of source/destination
ip addresses and/or ports.
It enables you to express policies like `10kpps for any given
destination IP' or `500pps from any given source IP' with a single
IPtables rule.
