Seems like this code isn't quite correct.  You are calling ipv6_add_dev 
for slave devices, and if I understand things correctly I don't believe 
that was happening before and may be an unintended side effect.

Ah, btw., autoconf and ipv6 operation on IFF_SLAVE devices is actually
desired nowadays and don't think we can change this. See also:
<https://patchwork.ozlabs.org/patch/531196/>

	IPv6 addrconf on IFF_SLAVE devices was disabled for bonding
slaves in commit c2edacf80e15 because it caused issues with snooping
switches.

	This is also referenced in

https://bugzilla.redhat.com/show_bug.cgi?id=236750

	Won't re-enabling autoconf on IFF_SLAVE devices cause that issue
to return?
