   Setup the MSI-X capability structure of device function with the number
   of requested irqs upon its software driver call to request for
   MSI-X mode enabled on its hardware device function. A return of zero
   indicates the successful configuration of MSI-X capability structure
   with new allocated MSI-X irqs. A return of &lt; 0 indicates a failure.
   Or a return of &gt; 0 indicates that driver request is exceeding the number
   of irqs or MSI-X vectors available. Driver should use the returned value to
   re-send its request.
