8. Vendor and device identifications
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
One is not required to add new device ids to include/linux/pci_ids.h.
Please add PCI_VENDOR_ID_xxx for vendors and a hex constant for device ids.
Do not add new device or vendor IDs to include/linux/pci_ids.h unless they
are shared across multiple drivers. You can add private definitions in
your driver if they're helpful, or just use plain hex constants.
PCI_VENDOR_ID_xxx constants are re-used. The device ids are arbitrary
hex numbers (vendor controlled) and normally used only in a single
location, the pci_device_id table.
