+ load-balancing router/server/switch. Basically, this match returns
+ true when the packet must be handled by this cluster node. Thus,
+ all nodes see all packets and this match decides which node handles
+ what packets. The work-load sharing algorithm is based on source
+ address hashing.
+
+ This module is usable for ipv4 and ipv6.
+
+ To use it also enable iptables-mod-cluster
+
+ see `iptables -m cluster --help` for more information.
