Comment 4 for bug 1235029

We use OL6.3. overlapping IPs don't work with this distro. FWIW OL6 still use kernel 2.6.39.

If this flag is enabled, neutron use ip command with netns argument which doesn't exist until iproute 3.1.0. We use iproute 2.6 with OL6 and it doesn't have support for network namespace.

Tempest shouldn't depend on this flag. This test should be fixed to create network with different cidr, I think.
