- * Special thanks goes to the I2O LAN driver people at the

- * A huge debt of gratitude is owed to David S. Miller (DaveM)
- * for fixing much of the stupid and broken stuff in the early

- * A really huge debt of gratitude is owed to Eddie C. Dost
- * for gobs of hard work fixing and optimizing LAN code.
