support os+odl for ipv6brahmaputra.1.0

As we known, the network of os+odl scenario is still not available.
so this patch still need to do more debug work.
however, Jan 19th is code freeze day, i think a good way is to merge it at first
when os+odl become available, i will do rest debug work and fix it
