Ok, can you step back and try to explain what problem you are trying to
solve first, before getting bogged down in odd details?  I find it
highly unlikely that this is something "unique", but I could be wrong as
I do not understand what you are wanting to do here at all.

We want to add two new sysfs files:

  sriov_vf_total_msix, for PF devices
  sriov_vf_msix_count, for VF devices associated with the PF

AFAICT it is *acceptable* if they are both present always.  But it
would be *ideal* if they were only present when a driver that
implements the ->sriov_get_vf_total_msix() callback is bound to the
PF.

BTW, we already have all possible combinations: static, static with
folder, with and without "sriov_" prefix, dynamic with and without
folders on VFs.

I need to know on which version I'll get Acked-by and that version I
will resubmit.

Thanks
