Subject: [PATCHv2 1/3] usbnet: specify naming of usbnet_set/get_link_ksettings
The old generic functions assume that the devices includes
an MDIO interface. This is true only for genuine ethernet.
Devices with a higher level of abstraction or based on different
technologies do not have it. So in preparation for
supporting that, we rename the old functions to something specific.
v2: adjusted to recent changes
