From 8265abc082d2283b4ef20237efadb71c6f16ed0c Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 21 Jul 2006 15:09:55 -0700 Subject: [IPV4]: Fix nexthop realm dumping for multipath routes Routing realms exist per nexthop, but are only returned to userspace for the first nexthop. This is due to the fact that iproute2 only allows to set the realm for the first nexthop and the kernel refuses multipath routes where only a single realm is present. Dump all realms for multipath routes to enable iproute to correctly display them. Signed-off-by: Patrick McHardy Signed-off-by: David S.
