NAME
       pci_enable_msi_range - configure device's MSI capability structure

SYNOPSIS
       int pci_enable_msi_range(struct pci_dev * dev, int minvec, int maxvec);

ARGUMENTS
       dev
           device to configure

       minvec
           minimal number of interrupts to configure

       maxvec
           maximum number of interrupts to configure

DESCRIPTION
       This function tries to allocate a maximum possible number of interrupts in a range between
       minvec and maxvec. It returns a negative errno if an error occurs. If it succeeds, it
       returns the actual number of interrupts allocated and updates the dev's irq member to the
       lowest new interrupt number; the other interrupt numbers allocated to this device are
       consecutive.
