2.4.21. Both ERR_COR and ERR_FATAL messages are sent when TLP with ECRC error is received

Description

In the GTS AXI Streaming IP for PCIe, if the ECRC Error Severity field of the Uncorrectable Error Severity register is set, both ERR_COR and ERR_FATAL messages are sent when a TLP with ECRC error is received. The ECRC error is reported as correctable as well as fatal instead of fatal when the ECRC error severity is fatal. The Advisory Non-Fatal Error Status field of the Correctable Error Status register is set incorrectly. However, masking the Advisory Non-Fatal Error does not prevent the generation of ERR_COR message. In this situation, it is safe to clear the Advisory Non-Fatal Error and ignore the ERR_COR message.

Workaround

None.
