  ipv6_stub_impl.ipv6_dst_lookup seems to require sk today.
But it only needs it to get 'net' in the beginning and sk is optional 
afterwards.
I will submit a patch to add 'net' as an arg  to ipv6_dst_lookup.
Users of ipv6_dst_lookup are few and that seems like an easy change and 
helps my patch.
If you or others think otherwise, pls let me know.
