Comment 1 for bug 1541802

this is for the v2 agent namespace driver.

looking at the code here:

https://github.com/openstack/neutron-lbaas/blob/master/neutron_lbaas/drivers/haproxy/namespace_driver.py#L314-L319

Looks like if the subnet has no gateway then it'll use the host routes. If it does have a gateway then it will not configure the host routes.
