If we try to setup an fake IRQ handler for legacy interrupts for devices that only have MSI-X (most if not all SR-IOV cards), we will fail with this: pciback[0000:01:10.0]: failed to install fake IRQ handler for IRQ 0! (rc:-38) Since those cards don't have anything in dev->irq. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
