Ramon,

Looks like my patch only works for DM_ETH. If I were to implement this
for legacy eth it would probably be a mess as the device list is a
static struct in net/eth_legacy.c. I'm not sure how to tell how many
boards are out there that are not yet converted to DM_ETH and am not
sure when legacy eth goes away. How about if I just add #ifdef
CONFIG_DM_ETH around the whole thing and it isn't supported for legacy
eth?

Best Regards,

Tim
