I can see this making sense as a feature bit that says VFs are not
initialized by default and must first be setup through an admin command.
This will likely need to be a feature bit because it's changing
behaviour outside of admin commands.
Then, we can have:
ADMIN_SETUP VF#
ADMIN_CLEANUP VF#
I like this because this generalizes CREATE/DESTROY that SIOV guys proposed.
Why do we need an id as a level of indirection though? What is wrong
with just using VF# directly?
