mac80211: allow drivers to access IPv6 information
To be able to implement NS response offloading (in regular operation or while in WoWLAN) drivers need to know the IPv6 addresses assigned to interfaces. Implement an IPv6 notifier in mac80211 to call the driver when addresses change. Unlike for IPv4, implement it as a callback rather than as a list in the BSS configuration, that is more flexible.
