Hi,
Look at the linux git code the driver use this function to fill the mac address of your net, and so I think that somenthing fail here. Maybe is not valid? Try to verify if it fails.
const void *of_get_mac_address(struct device_node *np) { struct property *pp;
pp = of_find_property(np, "mac-address", NULL); if (pp && (pp->length == 6) && is_valid_ether_addr(pp->value)) return pp->value;
pp = of_find_property(np, "local-mac-address", NULL); if (pp && (pp->length == 6) && is_valid_ether_addr(pp->value)) return pp->value;
pp = of_find_property(np, "address", NULL); if (pp && (pp->length == 6) && is_valid_ether_addr(pp->value)) return pp->value;
return NULL; }
