A driver needs to provide a dev_node_t structure for each device
on a card. In some cases, there is only one device per card (for
example, ethernet cards, modems). In other cases, there may be
many actual or logical devices (SCSI adapters, memory cards with
multiple partitions). The dev_node_t structures need to be kept
