Subject: [PATCH 4/4] IPv6: only notify protocols if address is compeletely gone
Date: Mon, 12 Apr 2010 08:41:34 -0700 [thread overview]

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.
