3.3. TX Credit Interface

The Transaction Layer TX interface transmits TLPs in the same order as they were received from the Application. To optimize performance, the Application can perform credit-based checking before submitting requests for transmission, allowing the Application to reorder packets to improve throughput. Application reordering is optional. The Transaction Layer always performs a credit check before transmitting any TLP.
