Sure, I got it. That's the point of this patch isn't it? :p
+     /*  Turn PHY off */ 
+     bmcr = jme_mdio_read(jme->dev, jme->mii_if.phy_id, MII_BMCR); 
+     bmcr |= BMCR_PDOWN; 
+     jme_mdio_write(jme->dev, jme->mii_if.phy_id, MII_BMCR, bmcr); 
+     /*  Turn PHY on */ 
+     bmcr = jme_mdio_read(jme->dev, jme->mii_if.phy_id, MII_BMCR); 
+     bmcr &= ~BMCR_PDOWN; 
+     jme_mdio_write(jme->dev, jme->mii_if.phy_id, MII_BMCR, bmcr); 
But what I mean is this part of the code.
