This looks like useful stuff to have, but I'd prefer that you put the 
check logic in board_eth_init() rather than adding to the individual 
device drivers.  I know the 8260 SCC driver is the older style, which 
precludes the use of board_eth_init, but I'll convert it if you're able 
to test.

regards,
Ben
