From 8595805aafc8b077e01804c9a3668e9aa3510e89 Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Mon, 12 Apr 2010 05:41:34 +0000 Subject: [PATCH] IPv6: only notify protocols if address is compeletely gone The notifier for address down should only be called if address is completely gone, not just being marked as tentative on link transistion. The code in net-next would case bonding/sctp/s390 to see address disappear on link down, but they would never see it reappear on link up. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
