+ ***************************************************************************
+ * Rewritten, heavily based on smsc911x simple driver by SMSC.
+ * Partly uses io macros from smc91x.c by Nicolas Pitre
+ *
+ * Supported devices:
+ *   LAN9115, LAN9116, LAN9117, LAN9118
+ *   LAN9215, LAN9216, LAN9217, LAN9218
+ *
+ * History:
+ *   05/05/2005 bahadir.balban@arm.com
+ *     - Transition to linux coding style
+ *     - Platform driver and module interface
+ *
+ *   17/07/2006 steve.glendinning@smsc.com
+ *     - Added support for LAN921x family
+ *     - Added workaround for multicast filters
+ *
+ *   31/07/2006 steve.glendinning@smsc.com
+ *     - Removed tasklet, using NAPI poll instead
+ *     - Multiple device support
+ *     - Large tidy-up following feedback from netdev list
+ *
+ *   03/08/2006 steve.glendinning@smsc.com
+ *     - Added ethtool support
+ *     - Convert to use generic MII interface
+ *
+ *   04/08/2006 bahadir.balban@arm.com
+ *     - Added ethtool eeprom r/w support
+ *
+ *   17/06/2007 steve.glendinning@smsc.com
+ *     - Incorporate changes from Bill Gatliff and Russell King
+ *
+ *   04/07/2007 steve.glendinning@smsc.com
+ *     - move irq configuration to platform_device
+ *     - fix link poller after interface is stopped and restarted
