Subject: Disappearing RFC3041 IPv6 privacy addresses

Starting (I believe) with kernel 3.17, I am seeing RFC3041 IPv6 privacy
addresses disappear while they are still in use.  I have been seeing
open SSH connections drop, and have finally seen one "dead" but not yet
closed.  At that point "ss -t" shows an ESTAB socket with a local
address that is no longer listed by "ip -6 addr list br1".

This is on a Fedora 20 system, currently running the Fedora
3.17.7-200.fc20.x86_64 kernel.  I don't know if it matters, but my
network setup is a router running OpenWRT and just IPv6 RAs and SLAAC
(DHCPv6 disabled).
