18 Connection tracking keeps a record of what packets have passed
19 through your machine, in order to figure out how they are related
20 into connections.

22 This is IPv6 support on Layer 3 independent connection tracking.
23 Layer 3 independent connection tracking is experimental scheme

35 packets which enables users to receive the filtered packets
36 with QUEUE target using libipq.
37
38 This option enables the old IPv6-only "ip6_queue" implementation
39 which has been obsoleted by the new "nfnetlink_queue" code (see
40 CONFIG_NETFILTER_NETLINK_QUEUE).
