Bug description:
[Impact]
RX speed on Intel ethernet I219 v6 is extremely slow due to multiple RX
CRC errors.
[Fix]
Disable e1000e K1 feature to make I219 and PCH operate at higher speed
to avoid the issue.
[Test]
Before applying the patch, the RX is slower than 150Kbps. After applying
the fix the RX speed can achive gigabits.
[Regression Potential]
Low. This only applies to recent I219 generations.
I've also test several other systems with e1000e and I don't see any
regression.
