Also this isn't quite correct. Target link speed is what the device tries to train. A device can try to train to much lower speed than the maximum on purpose. It makes sense to print this if the speed that platform wants via target link speed is different from what is actually established though. -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
