NAME
pci_enable_msi_range - configure device's MSI capability structure

int pci_enable_msi_range(struct pci_dev * dev, int minvec, int maxvec);
ARGUMENTS
dev
device to configure
minvec

maxvec
maximum number of interrupts to configure
DESCRIPTION
This function tries to allocate a maximum possible number of interrupts in a range between

returns the actual number of interrupts allocated and updates the dev's irq member to the
