A different, driver-specific solution could be like this (tested and working):

--- a/drivers/net/ethernet/marvell/mvneta.c
+++ b/drivers/net/ethernet/marvell/mvneta.c
@@ -5690,6 +5690,7 @@ static int mvneta_probe(struct platform_device *pdev)
        /* 9676 == 9700 - 20 and rounding to 8 */
        dev->max_mtu = 9676;
 
+       netif_carrier_off(dev);
        err = register_netdev(dev);
        if (err < 0) {
                dev_err(&pdev->dev, "failed to register\n");


Would that be the "correct" approach?
