usbnet: improve generic ethtool support

Browse Source 
This adds generic support for the ethtool commands get_settings,
set_settings, get_link and nway_reset to usbnet. These are now
implemented using mii functions when a low-level driver supports
mdio_read/mdio_write and does not override the usbnet ethtool
commands with its own.

Currently, this applies to the asix and the mcs7830 drivers.
I have tested it on mcs7830.
