The flags argument should normally be set to 0, but can be used to pass the

PCI_IRQ_NOMSI and PCI_IRQ_NOMSIX flag in case a device claims to support

MSI or MSI-X, but the support is broken, or to pass PCI_IRQ_NOLEGACY in

case the device does not support legacy interrupt lines.



By default this function will spread the interrupts around the available

CPUs, but this feature can be disabled by passing the PCI_IRQ_NOAFFINITY

flag.

The flags argument is used to specify which type of interrupt can be used

by the device and the driver (PCI_IRQ_LEGACY, PCI_IRQ_MSI, PCI_IRQ_MSIX).

A convenient short-hand (PCI_IRQ_ALL_TYPES) is also available to ask for

any possible kind of interrupt.  If the PCI_IRQ_AFFINITY flag is set,

pci_alloc_irq_vectors() will spread the interrupts around the available CPUs.
