The driver has a status method for receiving speed updates.
The framework, however, had support functions only for devices
that reported their speed upon an explicit query over a MDIO
interface.
CDC_NCM however gets direct notifications from the device.
As new support functions have become available, we shall now
record such notifications and tell the usbnet framework
to make direct use of them without going through the PHY layer.
v2: rebased on upstream
v3: changed variable names
