So this adds a lot of code to work around the issues you introduced by
unnecessarily blacklisting the CDC ECM configuration earlier, and still
makes the r8152 driver handle the device even in ECM mode.

Sorry, but this is a total mess.

Just remove the completely unnecessary blacklist, and let the cdc_ether
driver handle the device if the user selects the ECM configuration.
That't how the USB system works.  There is no need for any code in r8152
to do that.
