Sorry for attempting to bloat the dummy module. The intention was to be
able to add many dummy interfaces directly into a group without much
user-kernel communication.

However, I think that can be done by moving the existing (hopefully few)
interfaces to another group prior to adding the dummies to group 0 and
using that to manipulate them.
