Mike Frysinger 2bfa0f0c9a netdev: bfin_mac: handle timeouts with the MDIO registers gracefully
Have the low level MDIO functions pass back up timeout information so we
don't waste time polling them multiple times when there is a problem, and
so we don't let higher layers think the device is available when it isn't.
