[Impact]
To pass the energy star cert, the ASPM feature on RTL NIC should be enabled.
[Fix]
Enable the ASPM feature on all new Dell platforms, the family names are used on the new Dell platforms.
Alienware
Dell Laptops
Dell Pro Laptops
Dell Pro Max Laptops
Dell Desktops
Dell Pro Desktops
Dell Pro Max Desktops
Dell Pro Rugged Laptops
Dell Pro Precision
Dell Pro Essential
Dell Pro Education
XPS
[Test]
1. check the value of /sys/power/suspend_stats/total_hw_sleep
2. suspend and resume the system
3. the value of /sys/power/suspend_stats/total_hw_sleep increases
[Where problems could occur]
The listed family names are used in the new Dell platforms, so should not
impact the existing platforms. And Dell will push Realtek to fix the ASPM
issue found on RTL NIC.
