integer that indicates the type of this <a href="194f8fff-d903-44b7-9530-c66f5366f8c7" data-linktype="relative-path">COMM_PACKET</a> element. MUST
be set to 0x000C.</p><p><b>Length:</b>   A 32-bit, unsigned integer
that indicates the length in bytes of the data following the Length field. MUST
be 0x00000008.</p><p><b>Data:</b>   A 64-bit, unsigned integer
that specifies the offset of the data block in the staged file. Large staged
files require multiple packets to transfer. The offset here is relative to the
first byte of the staged file.</p></div>
