From 9bb5a14813f502b867a45075c88bc1f2b78381df Mon Sep 17 00:00:00 2001 From: =?utf8?q?YOSHIFUJI=20Hideaki=20/=20=E5=90=89=E8=97=A4=E8=8B=B1?= =?utf8?q?=E6=98=8E?= Date: Thu, 17 Jan 2013 12:53:48 +0000 Subject: [PATCH] ipv6: Introduce rt6_nexthop() to select nexthop address. For RTF_GATEWAY route, return rt->rt6i_gateway. Otherwise, return 2nd argument (destination address). This will be used by following patches which remove rt->n dependency patches in ip6_dst_lookup_tail() and ip6_finish_output2(). Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S.
