+/**
+ * This is a full rewrite of the pciDriver.
+ * New default is to support kernel 2.6, using kernel 2.6 APIs.
+ * 
+ * This header defines the interface to the outside world.
+ * 
+ * $Revision: 1.6 $
+ * $Date: 2008-01-24 14:21:36 $

+ * Change History:
+ * 
+ * $Log: not supported by cvs2svn $
+ * Revision 1.5  2008-01-11 10:15:14  marcus
+ * Removed unused interrupt code.
+ * Added intSource to the wait interrupt call.
+ *
+ * Revision 1.4  2006/11/17 18:44:42  marcus
+ * Type of SG list can now be selected at runtime. Added type to sglist.
+ *
+ * Revision 1.3  2006/11/17 16:23:02  marcus
+ * Added slot number to the PCI info IOctl.
+ *
+ * Revision 1.2  2006/11/13 12:29:09  marcus
+ * Added a IOctl call, to confiure the interrupt response. (testing pending).
+ * Basic interrupts are now supported.
+ *
+ * Revision 1.1  2006/10/10 14:46:52  marcus
+ * Initial commit of the new pciDriver for kernel 2.6
+ *
+ * Revision 1.7  2006/10/06 15:18:06  marcus

+ *
+ * Revision 1.6  2006/09/25 16:51:07  marcus
+ * Added PCI config IOctls, and implemented basic mmap functions.
