Detailed Description
Override the default behaviour of sendDeferredPacket to enable the memory-side cache port to also send requests based on the current MSHR status.
This queue has a pointer to our specific cache implementation and is used by the MemSidePort.

Check if there is a conflicting snoop response about to be send out, and if so simply stall any requests, and schedule a send event at the same time as the next snoop response is being sent out.
