Advisory 4 SRIO Outbound ACKID Issue
Revision(s) Affected: 1.3, 1.2, 1.1, 1.0
Details: The OUTBOUND_ACKID field of the RIO_SP(n)_ACKID_STAT register should be
updated by hardware each time a packet is sent out. The value should reflect the
ACKID value to be used on the next transmit packet. This field is being updated by
hardware as expected. The field can be also written by software and these writes also
succeed. However, a hardware error prevents this field from being read. The
OUTBOUND_ACKID will always read as 0. This problem does not impact link
operation.
Workaround 1: There is no workaround for this advisory.
