//
//    ABSTRACT:
//
//      This file contains IOCTL definitions for the OSR Sample
//      PCI Busmaster DMA device driver for the AMCC 5933 chip.
//
//		The point of putting these IOCTL definitions in a file all by themselves
//		is that the file can be used by both the driver and by user applications
//		that might use these IOCTLs.  User applications need to ensure that
//		winioctl.h is #included before this file.
