12.6.2.9 Quadlet Receive
The quadlet receive formats are shown below. The first quadlet contains the destination node ID and the rest of the packet header. The second
and third quadlets contain 16-bit source ID and either the 48-bit, quadlet-aligned destination offset (for requests) or the response code (for
responses). The fourth quadlet is the quadlet data for read responses and write quadlet requests, and is the data length and reserved for block
read requests. The last quadlet contains packet reception status.
