Lenovo Thunderbolt 4 Dock, and other Lenovo USB Docks are using the original
Realtek USB ethernet Vendor and Product IDs
If the Network device is Realtek verify that it is on a Lenovo USB hub
before enabling the passthru feature
This also adds in the device IDs for the Lenovo USB Dongle and one other
USB-C dock
