 * Copyright (C) 1996, 2006, 2008 David S. Miller (davem@davemloft.net)

 *

 * A lot of this driver was directly stolen from Erik H. Moe's PCI

 * Qlogic ISP driver.  Mucho kudos to him for this code.

 *

 * An even bigger kudos to John Grana at Performance Technologies

 * for providing me with the hardware to write this driver, you rule

 * John you really do.
