From ea6e574e34779fbb4526b2160411c163eac25323 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 5 Sep 2011 16:05:44 +0200 Subject: [PATCH] ipv6: add ip6_route_lookup like rt6_lookup, but allows caller to pass in flowi6 structure. Will be used by the upcoming ipv6 netfilter reverse path filter match. Signed-off-by: Florian Westphal Acked-by: David S.
