From 5dbb9c78c903467482113d214d12f983e4e4c6c4 Mon Sep 17 00:00:00 2001 From: Florian Obser Date: Fri, 3 Aug 2018 09:11:57 +0000 Subject: Account when the next nd6_timer_to is scheduled in nd6_timer() otherwise nd6_llinfo_settimer() might wrongly assume that a timeout is already scheduled earlier and not schedule one itself. This in turn lead to the neighbor cache no longer updating because neighbor solicitations were not send. Observed by many.
