When the UPI links would like to change power state, the Tx side initiates a request to the Rx side requesting to change states.  This requests can either be accepted or denied.  If the Rx side replies with an Ack, the power mode will change.  If it replies with NAck, no change will take place.  This can be filtered based on Rx and Tx.  An Rx LinkReqAck refers to receiving an Ack (meaning this agent's Tx originally requested the power change).  A Tx LinkReqAck refers to sending this command (meaning the peer agent's Tx originally requested the power change and this agent accepted it).",
