usbnet: add method for reporting speed without MII
The old method for reporting link speed assumed a driver uses the generic phy (mii) MDIO read/write functions. CDC devices don't expose the phy. Add a primitive internal version reporting back directly what the CDC notification/status operations recorded. v2: rebased on upstream v3: changed names and made clear which units are used v4: moved hunks to correct patch; rewrote commmit messages Signed-off-by: Oliver Neukum <oneukum@suse.com> Tested-by: Roland Dreier <roland@kernel.org> Reviewed-by: Grant Grundler <grundler@chromium.org> Tested-by: Grant Grundler <grundler@chromium.org> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
