* In the CM we have always ignored the BW settings on a shared lan,
  since there is no way to set the properties in geni-lib for such a
  lan. There is the local hack I added (linkwide properties), but that
  was also ignored for shared vlans. Now I am looking to see if there is
  a bandwidth specification there, and using that. I assume we do not
  care about delay/loss since well, we never have before.

* But even so, the mapper was ignoring it too. But we also have the code
  that tries to not use 10G interfaces unless explicitly asked for a 10G
  link, and that is not in the shared vlan path. So ... I made a few
  changes, the worst that can happen is that I broke share vlans for
  everyone except this one case.
