Comment 20 for bug 1237807

I was trying to explain that the admin_status_up should behave in the same manner for all the components, routers, ports, networks, subnetworks, etc. Which as I do understand it is that if it is false, it does not work. Since it is disabled. To be honest this change have bene introduced from havana to icehouse, and now we are in juno moving to kilo, so most of current users are aware that in the case of the network, admin_State_up does, nothing, which rises the question, of shall we remove it?
