    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
    in a linked list starting at the 'dev' field of a dev_link_t
    structure.  We allocate them in the card's private data structure,
    because they generally shouldn't be allocated dynamically.

    In this case, we also provide a flag to indicate if a device is
    "stopped" due to a power management event, or card ejection.  The
    device IO routines can use a flag like this to throttle IO to a
    card that is not ready to accept it.
