NAME
       pci_enable_msix_range - configure device's MSI-X capability structure

SYNOPSIS
       int pci_enable_msix_range(struct pci_dev * dev, struct msix_entry * entries, int minvec,
                                 int maxvec);

ARGUMENTS
       dev
           pointer to the pci_dev data structure of MSI-X device function

       entries
           pointer to an array of MSI-X entries

       minvec
           minimum number of MSI-X irqs requested

       maxvec
           maximum number of MSI-X irqs requested

DESCRIPTION
       Setup the MSI-X capability structure of device function with a maximum possible number of
       interrupts in the range between minvec and maxvec upon its software driver call to request
       for MSI-X mode enabled on its hardware device function. It returns a negative errno if an
       error occurs. If it succeeds, it returns the actual number of interrupts allocated and
       indicates the successful configuration of MSI-X capability structure with new allocated
       MSI-X interrupts.
