I see. We can probably use nf_route() instead.

Or if needed, use struct nf_ipv6_ops for this.

        if (v6ops)
                ret = v6ops->route_xyz(...);

@Alin: Would you send us a patch to do so to fix a3419ce3356cf1f
netfilter: nf_conntrack_sip: add sip_external_media logic".

This direct dependency with IPv6 is superfluous, it should not happen.

Thanks!
