Bug Description
[Impact]
If mac passthrough is enbled, Realtek USB ethernet (r8152) doesn't work
under the following steps:
1. Connect to a Dell dock
2. Suspend the system
3. Re-plug the dock
4. Resume the system
5. Ethernet stops working
[Fix]
The USB port lose its power when the dock gets replugged, so we need to
re-write the MAC address at reset_resume callback.
[Test]
The fix is succesfully tested on Dell WD15 dock and TB16 dock.
[Regression Potential]
Low. The fix limits to one single device and only take affect when MAC
passthrough is enabled.
