|struct pci_dev * dev,|
|struct msix_entry * entries,|
struct pci_dev * dev
pointer to the pci_dev data structure of MSI-X device function
struct msix_entry * entries
pointer to an array of MSI-X entries
minimum number of MSI-X irqs requested
maximum number of MSI-X irqs requested
Setup the MSI-X capability structure of device function with a maximum
possible number of interrupts in the range between
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.
