4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Hannes Frederic Sowa <hannes@xxxxxxxxxxxxxxxxxxx>
[ Upstream commit 9b29c6962b70f232cde4076b1020191e1be0889d ]
Bjørn reported that while we switch all interfaces to privacy stable mode
when setting the secret, we don't set this mode for new interfaces. This
does not make sense, so change this behaviour.
Fixes: 622c81d57b392cc ("ipv6: generation of stable privacy addresses for link-local and autoconf")
