The emac driver uses the mac_addr stuffed into the pdata, and defaults
to a random mac only if the pdata mac is invalid. It seems to be doing
the right thing at probe:
...
memcpy(priv->mac_addr, pdata->mac_addr, 6);
...
if (!is_valid_ether_addr(priv->mac_addr)) {
/* Use random MAC if none passed */
random_ether_addr(priv->mac_addr);
printk(KERN_WARNING "%s: using random MAC addr: %pM\n",
__func__, priv->mac_addr);
}
...
Could you verify that the pdata mac is correctly populated (from eeprom)
before emac probe happens?
Regards
Cyril.
