Bug description:
[Impact]
I210 may not reach maximum speed on Intel Alder Lake platforms.
[Fix]
Following the datasheet to ensure I210 is not in idle state when CPU is
using PCIe link to perform TX.
[Test]
With the fix applied, the I210 TX/RX speed can reach ~94x MBps.
[Where problems could occur]
Since this changes how hardware idles, it can slightly increase power
consumption.
