Indeed it does, thanks!  I didn't need to run iw under the container, it
appeared there instantly after moving the interface from the host.  I don't
know what you mean by adding vifs to the moved interface, but thanks for the
advice. :)

However, I think this should be automatically set up by the "lxc.network.type
= phys" option, so if no one has a clear reason of why this isn't supported
I'll file a new issue in the tracker.
