- * Special thanks goes to the I2O LAN driver people at the
- * University of Helsinki, who, unbeknownst to them, provided
- * the inspiration and initial structure for this driver.
- *
- * A huge debt of gratitude is owed to David S. Miller (DaveM)
- * for fixing much of the stupid and broken stuff in the early
- * driver while porting to sparc64 platform. THANK YOU!
- *
- * A really huge debt of gratitude is owed to Eddie C. Dost
- * for gobs of hard work fixing and optimizing LAN code.
- * THANK YOU!
