Cavium thinks it's a good idea to violate the PCI spec. Disabled multi-function PCI devices might have active functions. Add devices here manually, as coreboot's PCI allocator won't find them otherwise...

pci_enable_msix - configure device's MSI-X capability structure @dev: pointer to the pci_dev data structure of MSI-X device function @entries: pointer to an array of MSI-X entries @nvec: number of MSI-X irqs requested for allocation by device driver

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. A return of < 0 indicates a failure. Or a return of > 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.
