Lower_Address[6:0]:
Lower Address.
This field is valid for completions only. For memory read completions, this 
is the byte address for the first enabled byte of data returned. For all other 
completions, this field is set to all 0’s.

ROS_V
0x0
Tag[7:0]:
Tag.
This field is valid for completions only. This field in combination with the 
Requester ID field form a unique Transaction ID. The value from the 
original request must be preserved into the completion.

0x0
ReqID[15:0]:
Requester ID.
This field is located here for completions only. It’s located elsewhere for 
memory, configuration, I/O, and message requests. 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.

0x0
ByteCnt[7:0]:
Byte Count.
This field is valid for completions only. For memory read completions, this 
specifies the remaining byte count to satisfy the request including the 
current packet payload. For all other completions, this field must be set to 
4. This field is concatenated with ByteCnt[11:8] to form ByteCnt[11:0].

ROS_V
0x0
CplStat[2:0]:
Completion Status.
This field is valid for completions only. This indicates the status for the 
completion, encoded as follows: 
3'b000: Successful Completion 
3'b001: Unsupported Request/Master Abort 
3'b010: Configuration Request Retry Status 
3'b100: Completer Abort 
All other encodings are reserved.

BCM:
Byte Count Modified.
This field is valid for completions only. This field is set only in initial 
completion packets and only by PCI-X completer. A value of “1” indicates 
that the Byte Count field reports only the size of the current packet.

ROS_V
0x0
ByteCnt[11:8]:
Byte Count.
This field is valid for completions only. This field is concatenated with 
ByteCnt[7:0] to form ByteCnt[11:0]. See description for ByteCnt[7:0].
47:32
ROS_V
0x0
CplID[15:0]:
Completer ID.
This field is valid for completions only. This uniquely identifies the 
completer and is comprised as follows: {device[4:0], function[2:0], 
bus[7:0]}.
