- ***************************************************************************
- * 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
- *
- * 13/07/2007 bahadir.balban@arm.com
- * - set irq polarity before requesting irq
- *
- * 26/06/2007 hennerich@blackfin.uclinux.org
