For new FRU and Non-FRU resources, plugins send an oh_event struct to the
infrastructure (see oh_event.h in source code).
This structure contains the SaHpiEventT (where you would put the hotswap
event information), the resource information (SaHpiRptEntryT), and a
linked list of the RDRs for that resource. For subsequent events regarding
that same resource, only the SaHpiEventT needs to be set within the
oh_event structure.
