Great, thanks.

Hm, that's a tricky one.

Off-hand, I'd say probably the best way to do this would be:

mac-address		Ethernet address
i82543-cfg1		CFG1 value
i82543-cfg2		CFG2 value
i82543-swdpin		SWDPIN value

I'm not particularly keen on constructing an entire EEPROM blob for  
an Ethernet chip in platform-specific code.

Besides, individual properties gives you the flexibility to use e.g.  
an implementation-specific SWDPIN value even if the device has an  
otherwise valid EEPROM.
