ipv6_get_ifaddr() not exported

[Valentine Sinitsyn]

Hi all,

I'm working on a custom Netfilter module which could seemingly use 
ipv6_get_ifaddr() function to find a netdev which has a destination IPv6 
assigned (if any). The function is public, but not exported, so I can't 
use it in my module.

Am I doing anything wrong, or I'm just a first type to use 
ipv6_get_ifaddr() outside net/ipv6 code, and it's okay to export it now?

Thanks,
Valentine
