99 * The devclass object has two main functions in the system. The first
100 * is to manage the allocation of unit numbers for device instances
101 * and the second is to hold the list of device drivers for a
102 * particular bus type. Each devclass has a name and there cannot be
103 * two devclasses with the same name. This ensures that unique unit
104 * numbers are allocated to device instances.
106 * Drivers that support several different bus attachments (e.g. isa,
107 * pci, pccard) should all use the same devclass to ensure that unit
108 * numbers do not conflict.
110 * Each devclass may also have a parent devclass. This is used when
111 * searching for device drivers to allow a form of inheritance. When
112 * matching drivers with devices, first the driver list of the parent
113 * device's devclass is searched. If no driver is found in that list,
114 * the search continues in the parent devclass (if any).
