r6040: check PHY status when bringing interface up
This patch makes the driver properly initialize the PHY status if not correctly set by the bootloader/BIOS. It prevents some boards to bring up the link on boot. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
