DataHub.h
Abstract:
The data hub protocol is used both by agents wishing to log
data and those wishing to be made aware of all information that
has been logged.
For more information please look at Intel Platform Innovation
Framework for EFI Data Hub Specification.

// change and the HeaderSize will change if the definition of
// EFI_DATA_RECORD_HEADER is extended.

//
// The Data Hub driver is responcible for initializing:
// LogTime and LogMonotonicCount.
