Ok, I will revisit this patch after 2020.04.

I think we should probably let net_random_ethaddr() run unconditionally:

--- a/net/eth-uclass.c
+++ b/net/eth-uclass.c
@@ -547,15 +547,9 @@ static int eth_post_probe(struct udevice *dev)
                       dev->name);
        } else if (is_zero_ethaddr(pdata->enetaddr) ||
                   !is_valid_ethaddr(pdata->enetaddr)) {
-#ifdef CONFIG_NET_RANDOM_ETHADDR
                net_random_ethaddr(pdata->enetaddr);
                printf("\nWarning: %s (eth%d) using random MAC address - %pM\n",
                       dev->name, dev->seq, pdata->enetaddr);
-#else
-               printf("\nError: %s address not set.\n",
-                      dev->name);
-               return -EINVAL;
-#endif
        }

        eth_write_hwaddr(dev);

Thanks
