The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as a broken CDC device by default. Add the custom Lenovo PID to the r8152 driver to support it properly. Also, systems compatible with this dock provide a BIOS option to enable MAC address passthrough (as per Lenovo document "ThinkPad Docking Solutions 2017"). Add the custom PID to the MAC passthrough list too. Tested on a ThinkPad 13 1st gen with the expected results: passthrough disabled: Invalid header when reading pass-thru MAC addr passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX Signed-off-by: Jean-Francois Le Fillatre <jflf_kernel@gmx.com> Signed-off-by: David S.

commit 1bd3a383075c64d638e65d263c9267b08ee7733c upstream.

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as
a broken CDC device by default. Add the custom Lenovo PID to the r8152
driver to support it properly.

Also, systems compatible with this dock provide a BIOS option to enable
MAC address passthrough (as per Lenovo document "ThinkPad Docking
Solutions 2017"). Add the custom PID to the MAC passthrough list too.

Tested on a ThinkPad 13 1st gen with the expected results:

passthrough disabled: Invalid header when reading pass-thru MAC addr
passthrough enabled:  Using pass-thru MAC addr XX:XX:XX:XX:XX:XX
