The r815x family devices expose a vendor specific function which the r8152 interface driver wants to handle. This is the preferred device mode. Additionally one or more USB class functions are usually supported for hosts lacking a vendor specific driver. The choice is USB configuration based, with one alternate function per configuration.

Using the above example, Linux defaults to cfg #2, running the device in a sub-optimal NCM mode. Previously we've attempted to work around the problem by blacklisting the devices in the ECM class driver "cdc_ether", and matching on the ECM class function in the vendor specific interface driver. The latter has been used to switch back to the vendor specific configuration when the driver is probed for a class function. This workaround has several issues; - class driver blacklists is additional maintanence cruft in an unrelated driver - class driver blacklists prevents users from optionally running the devices in class mode - each device needs double match entries in the vendor driver - the initial probing as a class function slows down device discovery Now these issues have become even worse with the introduction of firmware supporting both NCM and ECM, where NCM ends up as the default mode in Linux. To use the same workaround, we now have to blacklist the devices in to two different class drivers and add yet another match entry to the vendor specific driver. This patch implements an alternative workaround strategy - independent of the interface drivers. It avoids adding a blacklist to the cdc_ncm driver and will let us remove the existing blacklist from the cdc_ether driver. As an additional bonus, removing the blacklists allow users to select one of the other device modes if wanted.
