Flow control types:
Transaction Types Initiated by The 82574
Transaction Types at the Tx Transaction Layer
1. The MAX_PAYLOAD_SIZE supported is loaded from the NVM (either 128 bytes or 256 bytes). Effective
Message Handling by The 82574 (as a Receiver)
Message packets are special packets that carry a message code.
The upstream device transmits special messages to the 82574 by using this
mechanism.
The transaction layer decodes the message code and responds to the message
accordingly.
