The definition of the ASPM support field in the Link Capabilities Register had been changed by the "ASPM optionality ECN" as follows: <Before> 00b Reserved 01b L0s Supported 10b Reserved 11b L0s and L1 Supported <After> 00b No ASPM Support 01b L0s Supported 10b L1 Supported 11b L0s and L1 Supported Current linux ASPM driver doesn't enable ASPM if the support field is 00b or 10b. So there is no impact about 00b. But current linux ASPM driver doesn't enable L1 if the support field is 10b. With this patch, 10b (L1 support) is handled properly.
