Yes, your patch does fix issues with IPv6 autoconfiguration in bridged networks completely. I've just tested it with and without STP. IPv4 DHCP continues to function correctly. It is definitely much cleaner solution than my hack. IPv6 autoconfiguration code already checks if NETDEV_CHANGE or NETDEV_UP represent a device that is ready to transmit data before attempting to configure the interface. No additional changes required there. This patch should also fix duplicate address detection of linklocal address on bridged interfaces that I believe was also broken prior to this patch.
