Comment 5 for bug 1596597

Ok, I did a fresh install on completely different hardware just to make sure that The issue still persists. I did a simple single interface with an untagged network and a single VLAN. The VLAN still does not work until I go to ENI and add the 'auto iface' to both places where it is missing.

Here is the requested data.
