Critical Issue
When the RapidIO II IP core IO Slave module receives a "Read Response without payload" response, and if this response has previously has been timed out by the IO slave module, then this response appears again on the IO slave interface (with readdata_valid and readdata_response asserted).
This is incorrect, as the response should not re-appear after timeout.
This issue has no workaround.
This issue is fixed in version 16.0 of the RapidIO II IP Core.
