From 876fd05ddbae03166e7037fca957b55bb3be6594 Mon Sep 17 00:00:00 2001 From: Hannes Frederic Sowa Date: Mon, 24 Jun 2013 00:22:20 +0200 Subject: ipv6: don't disable interface if last ipv6 address is removed The reason behind this change is that as soon as we delete the last ipv6 address of an interface we also lose the /proc/sys/net/ipv6/conf/ directory. This seems to be a usability problem for me. I don't see any reason why we should shutdown ipv6 on that interface in such cases.
