+This patch adds a new match called 'hashlimit'.
+The idea is to have something like 'limit', but either per
+destination-ip or per (destip,destport) tuple.
+It gives you the ability to express
+ '1000 packets per second for every host in'
+ '100 packets per second for every service of'
+with a single iptables rule.
