      PCI ASPM: support L1 only · 7557b5d6
      Kenji Kaneshige 提交于
      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.
