455  * BUS_PROBE_SPECIFIC is for devices that cannot be reprobed, and that no
456  * possible other driver may exist (typically legacy drivers who don't fallow
457  * all the rules, or special needs drivers).  BUS_PROBE_VENDOR is the
458  * suggested value that vendor supplied drivers use.  This is for source or
459  * binary drivers that are not yet integrated into the FreeBSD tree.  Its use
460  * in the base OS is prohibited.  BUS_PROBE_DEFAULT is the normal return value
461  * for drivers to use.  It is intended that nearly all of the drivers in the
462  * tree should return this value.  BUS_PROBE_LOW_PRIORITY are for drivers that
463  * have special requirements like when there are two drivers that support
464  * overlapping series of hardware devices.  In this case the one that supports
465  * the older part of the line would return this value, while the one that
466  * supports the newer ones would return BUS_PROBE_DEFAULT.  BUS_PROBE_GENERIC
467  * is for drivers that wish to have a generic form and a specialized form,
468  * like is done with the pci bus and the acpi pci bus.  BUS_PROBE_HOOVER is
469  * for those busses that implement a generic device place-holder for devices on
470  * the bus that have no more specific driver for them (aka ugen).
