Comment 4 for bug 1683824

@MJ, but routeable from the subnet is not implemented, right?
1. Take haproxy driver for example, the route exists in haproxy namespace is only that created by the vip port subnet. It has nothing to do with subnet.
2. Is it suitable, ease of use for end user to implement that cases you mention? and what cases invovled?
Thanks you very much, MJ.
