17	---help---
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.
21
22	  This is IPv6 support on Layer 3 independent connection tracking.
23	  Layer 3 independent connection tracking is experimental scheme
24	  which generalize ip_conntrack to support other layer 3 protocols.

30	depends on INET && IPV6 && NETFILTER
31	depends on NETFILTER_ADVANCED
32	---help---
33
34	  This option adds a queue handler to the kernel for IPv6
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).

55	help
56	  ip6tables is a general, extensible packet identification framework.
57	  Currently only the packet filtering and packet mangling subsystem
58	  for IPv6 use this, but connection tracking is going to follow.
59	  Say 'Y' or 'M' here if you want to use either of those.
