const bool MSHR::Target::allocOnFill

Should the response servicing this target list allocate in the cache?

bool MSHR::Target::markedPending

We use this flag to track whether we have cleared the downstreamPending flag for the MSHR of the cache above where this packet originates from and guard noninitial attempts to clear it.

The flag markedPending needs to be updated when the TargetList is in service which can be: 1) during the Target instantiation if the MSHR is in service and the target is not deferred, 2) when the MSHR becomes in service if the target is not deferred, 3) or when the TargetList is promoted (deferredTargets -> targets).
