A virtual base opaque structure used to hold state associated with the packet (e.g., an MSHR), specific to a MemObject that sees the packet.
A pointer to this state is returned in the packet's response so that the MemObject in question can quickly look up the state needed to process it. A specific subclass would be derived from this to carry state specific to a particular sending device.
As multiple MemObjects may add their SenderState throughout the memory system, the SenderStates create a stack, where a MemObject can add a new Senderstate, as long as the predecessing SenderState is restored when the response comes back. For this reason, the predecessor should always be populated with the current SenderState of a packet before modifying the senderState field in the request packet.
