SMSC LAN9500 has dual purpose GPIO/LED pins, and by default at power-on these are configured as GPIOs. This means that if LEDs are fitted they won't ever light. This patch sets them to be LED outputs for speed, duplex and link/activity. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>
