Create l2 interfaces in batch

[ogenstad]

One last thing...

• Also slight cleanup of interface names
• Due to the addition of batches the complexity went over the current limit. I just ignored this for now. There are a few additional cleanups that can be done here to avoid this but I'll save that part for later.
