4.12.4. Receive Interface

All TLPs received by the IP are transmitted to the application through the RX streaming interface (except Malformed TLPs). All PCIe* protocol errors leading up to designating a TLP as a good packet or not are detected by the Hard IP and communicated to user logic to take appropriate action in terms of error logging and escalation. The IP does not generate any error message internally since this is the responsibility of the user logic.
