12.6.2.4 Block Transmit
The block transmit format is shown below, this is the generic format for reads and writes. The first quadlet contains packet control information.
The second and third quadlets contain the 16-bit destination node ID 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 transaction). The block data, if any, follows the extended transaction code.
