886  * the name and type information.
887  *
888  * For a pure dynamic property to show up in a di_init() devinfo shapshot, the
889  * devinfo driver must know name and type. The i_ddi_prop_dyn_t mechanism
890  * allows a driver to define an array of the name/type information of its
891  * dynamic properties. When a driver declares its dynamic properties in a
892  * i_ddi_prop_dyn_t array, and registers that array using
893  * i_ddi_prop_dyn_driver_set() the devinfo driver has sufficient information
894  * to represent the properties in a snapshot - calling the driver's
895  * prop_op(9E) to obtain values.
896  *
897  * The last element of a i_ddi_prop_dyn_t is detected via a NULL dp_name value.
898  *
899  * A pure dynamic property name associated with a minor_node/dev_t should be
900  * defined with a dp_spec_type of S_IFCHR or S_IFBLK, as appropriate.  The
901  * driver's prop_op(9E) entry point will be called for all
902  * ddi_create_minor_node(9F) nodes of the specified spec_type. For a driver
903  * where not all minor_node/dev_t combinations support the same named
904  * properties, it is the responsibility of the prop_op(9E) implementation to
905  * sort out what combinations are appropriate.
906  *
907  * A pure dynamic property of a devinfo node should be defined with a
908  * dp_spec_type of 0.
909  *
910  * NB: Public DDI property interfaces no longer support pure dynamic
911  * properties, but they are still still used.  A prime example is the cmlb
912  * implementation of size(9P) properties. Using pure dynamic properties
913  * reduces the space required to maintain per-partition information. Since
914  * there are no public interfaces to create pure dynamic properties,
915  * the i_ddi_prop_dyn_t mechanism should remain private.
