Sharing hosts's namespace inside containers

I need to make host’s network namespace visible inside the containers. As mentioned in following post :

http://containerops.org/2013/11/19/lxc-networking/

I’m not quite clear that how to make equivalent configuration for :
lxc.network.type = none

available in profile to attach to a container.with a version 2.13

Any help will be appreciated.
