I suggest to use vendor mode only, but some people ask me to
submit such patches. If these patches are rejected, I have
enough reasons to tell them it is unacceptable rather than
I don't do it.

The pure cdc_ether driver couldn't change the speed of the
ethernet, because it doesn't know how to access the PHY of
the device. Therefore, I add relative code in r8152 driver.
