Currently, we can only print the phy_status. Factor out the routine to get the status, so we can query it from fec drivers and configure accordingly. Needed because mx28 needs a special bit set for 10Mbit. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
