With CONFIG_IPV6=m and CONFIG_NF_CONNTRACK_SIP=y, we now get a link failure:

net/netfilter/nf_conntrack_sip.o: In function `process_sdp':
nf_conntrack_sip.c:(.text+0x4344): undefined reference to `ip6_route_output_flags'

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".

nf_ip6_route(net, &dst, &fl6, false) seems to be appropriate.
I'll send the patch Monday.
