+Subject: r8152: add PID for the Lenovo OneLink+ Dock
+
+From: Jean-Francois Le Fillatre <jflf_kernel@gmx.com>
+
+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
