From 44c9f2f206f880c959fa4b43618e3f7fe2cd6157 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Sun, 7 Jan 2018 12:45:08 +0200 Subject: [PATCH] ipv6: Check nexthop flags in route dump instead of carrier Similar to previous patch, there is no need to check for the carrier of the nexthop device when dumping the route and we can instead check for the presence of the RTNH_F_LINKDOWN flag.
