Here's an example of what I'm trying to get at-- take 
a node from a FSL device tree.  The ideas I've heard
for expressing the class are like this--

#1  don't express any class at all:

  ucc@2200 {
        compatible = "fsl,ucc_geth";
        model = "UCC";
        device-id = <3>;
        reg = <2200 200>;
        interrupts = <22>;
        interrupt-parent = < &qeic >;
        mac-address = [ 00 00 00 00 00 00 ];
        local-mac-address = [ 00 00 00 00 00 00 ];
        rx-clock = <19>;
        tx-clock = <1a>;
        phy-handle = < &phy3 >;
        pio-handle = < &pio3 >;

Of course, this should properly be something like

ethernet@2200 {
	compatible = "fsl,mpc8360-qe-enet", "fsl,qe-enet";
	local-mac-address = [ 00 00 00 00 00 00 ];
	...
};

With no "mac-address", and a more useful "model" if any at all.
