This is done by the guest BIOS.
If I remove that line, my driver crashes when it falls back to
pin-based interrupts (when MSI is turned off). Is there something in
the device driver that I need to set in place of this? A number of
other devices (mostly network cards) set the interrupt pin this way,
so I'm a little confused.
Sorry, I confused this with PCI_INTERRUPT_LINE.
Note there is a helper to set it, pci_config_set_interrupt_pin().
