Thanks so much for the quick turn around!

So I dropped all the reverts you suggested, and applied this one
against 4.13-rc4, but I'm still seeing the problematic behavior.

# ip -6 route show
2601:1c2:1002:83f0::/64 dev eth0  proto kernel  metric 256  expires
345599sec pref medium
fe80::/64 dev eth0  proto kernel  metric 256  pref medium
default via fe80::200:caff:fe11:2233 dev eth0  proto ra  metric 1024
expires 1799sec hoplimit 64 pref medium


After unplugging the device (and getting the unregister_netdevice errors):
# ip -6 route show
#


thanks
