Hi Dave,

attached is a patch which introduces
* register_inet6addr_notifier
* unregister_inet6addr_notifier

and exports

* EXPORT_SYMBOL(ndisc_mc_map);
* EXPORT_SYMBOL(register_inet6addr_notifier);
* EXPORT_SYMBOL(unregister_inet6addr_notifier);

Purpose of this patch is to give drivers the possibility of learning, what
IP addresses are set in the stack. This is done for IPv4 in
net/ipv4/dev_inet.c, but is missing for IPv6. The feature is exploited by
cards which provide IP offload capabilities and therfore require knowledge
of IP addresses. ndisc_mc_map is also required for the IP-MAC handling of
those cards.

Could you please apply this, if there are no objections or otherwise tell
me, what needs to be done to get that knowledge otherwise?
(See attached file: register_inet6addr_notifier.diff.gz)

(sorry for the attachment, but my mail client would scramble the patch in
plain text :-(

Thanks,
Utz
