 * CAPI 2.0 defines & types
 * 
 * From CAPI 2.0 Development Kit AVM 1995 (capi20.h)
 * Rewritten for Linux 1996 by Carsten Paeth (calle@calle.in-berlin.de)
 * 
 * $Log: capiutil.h,v $
 * Revision 1.4  1999/09/15 08:16:03  calle
 * Implementation of 64Bit extention complete.
 *
 * Revision 1.3  1999/09/07 09:02:53  calle
 * SETDATA removed. Now inside the kernel the datapart of DATA_B3_REQ and
 * DATA_B3_IND is always directly after the CAPI message. The "Data" member
 * ist never used inside the kernel.
 *
 * Revision 1.2  1997/05/18 09:24:19  calle
 * added verbose disconnect reason reporting to avmb1.
 * some fixes in capi20 interface.
 * changed info messages for B1-PCI
 *
 * Revision 1.1  1997/03/04 21:50:35  calle
 * Frirst version in isdn4linux
 *
 * Revision 2.2  1997/02/12 09:31:39  calle
 * new version
