Using 0 on the switch side causes problems for the switch manager, but in this case, if we don't have a default_vid, then we aren't talking to the switch anyways. Thanks, Jake

We can probably drop this patch for now and if you want you can work this from our end as the out-of-tree code doesn't make the upstream and I would imagine you guys are planning to upstream that patch at some point. - Alex
