[BUG?] drivers: net:ethernet: cpsw: add support for VLAN

[Christoph Fritz]

Hi,

 has commit 3b72c2fe0c6bbec42e ("drivers: net:ethernet: cpsw: add
support for VLAN") introduced a bug by defining CPSW_VLAN_AWARE as
BIT(1) instead of BIT(2)?

+#define CPSW_VLAN_AWARE		BIT(1)
<snip>
 	/* switch to vlan unaware mode */
-	cpsw_ale_control_set(priv->ale, 0, ALE_VLAN_AWARE, 0);
+	cpsw_ale_control_set(priv->ale, priv->host_port, ALE_VLAN_AWARE,
+			     CPSW_ALE_VLAN_AWARE);
+	control_reg = readl(&priv->regs->control);
+	control_reg |= CPSW_VLAN_AWARE;
+	writel(control_reg, &priv->regs->control);

See TRM [1] page 1980 (14.5.1.2 CONTROL Register), there bit
CPSW_VLAN_AWARE is number 2.

I didn't do any tests, just stumbled upon.
