Thanks, that's the right direction. For the final patch I'd move it
to lan78xx_mac_link_up(), which is IMHO a bit "cleaner":

[...]
  static void lan78xx_rx_urb_submit_all(struct lan78xx_net *dev);
+static int lan78xx_write_vlan_table(struct lan78xx_net *dev);
[...]
static void lan78xx_mac_link_up(struct phylink_config *config,
[...]
  	if (ret < 0)
  		goto link_up_fail;

+	ret = lan78xx_write_vlan_table(dev);
+	if (ret < 0)
+		goto link_up_fail;
+
  	netif_start_queue(net);
[...]

Could you give this version a quick test and confirm? Then I'll add
your Tested-by.
