From 36dee24459ef6c7b4cbda4c748d974d45f8ba853 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 3 Aug 2017 13:28:22 +0200 Subject: [PATCH] ipv6: fib: Unlink replaced routes from their nodes When a route is deleted its node pointer is set to NULL to indicate it's no longer linked to its node. Do the same for routes that are replaced. This will later allow us to test if a route is still in the FIB by checking its node pointer instead of its reference count.
