[SRU] [B/D/E/OEM-B/OEM-OSP1-B] [PATCH 0/3] Fix non-working Realtek USB ethernet after system resume

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1847063

[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.

Kai-Heng Feng (1):
  r8152: Set macpassthru in reset_resume callback

Mario Limonciello (2):
  r8152: remove extra action copying ethernet address
  r8152: Refresh MAC address during USBDEVFS_RESET
