450  * Some convenience defines for probe routines to return.  These are just
451  * suggested values, and there's nothing magical about them.
452  * BUS_PROBE_SPECIFIC is for devices that cannot be reprobed, and that no
453  * possible other driver may exist (typically legacy drivers who don't fallow
454  * all the rules, or special needs drivers).  BUS_PROBE_VENDOR is the
455  * suggested value that vendor supplied drivers use.  This is for source or
456  * binary drivers that are not yet integrated into the FreeBSD tree.  Its use
457  * in the base OS is prohibited.  BUS_PROBE_DEFAULT is the normal return value
458  * for drivers to use.  It is intended that nearly all of the drivers in the
459  * tree should return this value.  BUS_PROBE_LOW_PRIORITY are for drivers that
460  * have special requirements like when there are two drivers that support
461  * overlapping series of hardware devices.  In this case the one that supports
462  * the older part of the line would return this value, while the one that
463  * supports the newer ones would return BUS_PROBE_DEFAULT.  BUS_PROBE_GENERIC
464  * is for drivers that wish to have a generic form and a specialized form,
465  * like is done with the pci bus and the acpi pci bus.  BUS_PROBE_HOOVER is
466  * for those busses that implement a generic device place-holder for devices on
467  * the bus that have no more specific driver for them (aka ugen).
