The USB nic have two configurations. One is the config 2 which is the ECM
mode and uses the driver of cdc_ether. The other is the config 1 which use
the driver of r8152. When the dangle is plugged, I find the configuration
is 2 and the ECM driver would be loaded. By this way, you could select
which mode you want to run. Some people would select ECM mode for
performance, and the other would select r8152 for power saving.
