Bug description:
[Impact]
Realtek r8169 has abysmal network speed.
[Fix]
Disable ASPM L1.2 because the device takes a long time to exit from
L1.2.
[Test]
Use `iperf` to test network speed.
When ASPM L1.2 gets disabled, TX and RX and reach ~700Mbps and ~900Mbps
respectively.
[Where problems could occur]
Disabling ASPM L1.2 can slightly increase power consumption. The CPU
package C-State seems to be unaffected so the increase is rather minor.
