Message-Id: <1348514369-3272-2-git-send-email-pablo@netfilter.org>

Subject: [PATCH 01/16] netfilter: fix IPv6 NAT dependencies in Kconfig
From: Pablo Neira Ayuso <pablo@...filter.org>
* NF_NAT_IPV6 requires IP6_NF_IPTABLES
* IP6_NF_TARGET_MASQUERADE, IP6_NF_TARGET_NETMAP, IP6_NF_TARGET_REDIRECT
and IP6_NF_TARGET_NPT require NF_NAT_IPV6.
This change just mirrors what IPv4 does in Kconfig, for consistency.
