From 1a72418bd7f0edcb85c817964efd370254fe749d Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Thu, 1 Nov 2012 22:58:22 +0000 Subject: [PATCH 1/1] ipv6/multipath: remove flag NLM_F_EXCL after the first nexthop fib6_add_rt2node() will reject the nexthop if this flag is set, so we perform the check only for the first nexthop.
