ipv6: add flowlabel_consistency sysctl
With the introduction of IPV6_FL_F_REFLECT, there is no guarantee of flow label unicity. This patch introduces a new sysctl to protect the old behaviour, enable by default. Changelog of V3: * rename ip6_flowlabel_consistency to flowlabel_consistency * use net_info_ratelimited() * checkpatch cleanups Signed-off-by: Florent Fourcot <florent.fourcot@enst-bretagne.fr> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.
