This field is located here only for memory, configuration, I/O, and
message requests. This field is located elsewhere for completions. This
field in combination with the Tag field form a unique Transaction ID. The
Requester ID is comprised as follows: {device[4:0], function[2:0],
bus[7:0]}. The value from the original request must be preserved into the
completion.

TD:
TLP Digest.
A value of “1” in this field indicates the presence of a single DW TLP digest
A value of “1” in this field indicates the presence of a single DW TLP digest
at the end of the packet for use in ECRC protection as defined by the
PCIe* specification.

These provide hints as to how the packet should be handled:
Bit 1 set to “1” indicates Relaxed Ordering.
Bit 0 set to “1” indicates No Snoop.
This field must be set to all 0’s for configuration requests, I/O requests,
message requests, and message signaled interrupts.
