Thanks for your positive response.

I imagined that a small patch series would be more reasonable
than this direct change combination.

Unfortunately, you interpreted my update suggestion in a questionable way
at this source code place.
I guess that the following code variant can be considered instead.

 	ether_addr_copy(nn->dp.netdev->perm_addr, mac_addr);
+	return;
+
+generate_random_address:
+	eth_hw_addr_random(nn->dp.netdev);
 }
