Does 'ifconfig eth0 media xxx' wind up calling dev->set_config?

If yes, my guess is correct, I think the proper solution is to:
* create a generic set_config, which does nothing but convert the calls'
semantics into ethtool semantics, and
* add ethtool support to the specific driver

And you might even go so far as to create a generic MII implementation
of ethtool support, so that existing drivers can simply plug in their
mdio_{read,write} functions to automatically get full ethtool support.
(disclaimer:  this is a spur-of-the-moment thought, creating a generic
MII module for ethtool support may not be feasible)

drivers/net/sis900.c implements set_config, if you want an example..

Finally, if you want to just use ethtool directly, grab the SRPM and
install it on your system.
