12.6.2.10 Block receive
The block receive format is 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 sourceID and either the 48-bit destination offset (for requests) or the response code and reserved data (for
responses). The fourth quadlet contains the length of the data field and the extended transaction code (all zeros except for lock transactions).
The block data, if any, follows the extended code. The last quadlet contains packet reception status.
