Don't we want pcibios_sriov_enable() to be able to crop the number
of VFs or do we think any resource limits have been applied
already ?

The second parameter "initial" is the number of VFs will be enabled.
Arch
dependent function will check the resources for these number of VFs.

Do I catch your question correctly?

I was wondering if the number of resource that can be enabled is
smaller, should the arch function be able to return that smaller
number and we would still enable that number ?

Ie, have the arch function be able to "update" the value of
"initial" (by passing it by pointer for example).
