 * Kernel CAPI 2.0 Interface for Linux
 * 
 * (c) Copyright 1997 by Carsten Paeth (calle@calle.in-berlin.de)
 * 
 * $Log: kernelcapi.h,v $
 * Revision 1.4  1999/09/10 17:24:19  calle
 * Changes for proposed standard for CAPI2.0:
 * - AK148 "Linux Exention"
 *
 * Revision 1.3  1999/07/01 15:26:56  calle
 * complete new version (I love it):
 * + new hardware independed "capi_driver" interface that will make it easy to:
 *   - support other controllers with CAPI-2.0 (i.e. USB Controller)
 *   - write a CAPI-2.0 for the passive cards
 *   - support serial link CAPI-2.0 boxes.
 * + wrote "capi_driver" for all supported cards.
 * + "capi_driver" (supported cards) now have to be configured with
 *   make menuconfig, in the past all supported cards where included
 *   at once.
 * + new and better informations in /proc/capi/
 * + new ioctl to switch trace of capi messages per controller
 *   using "avmcapictrl trace [contr] on|off|...."
 * + complete testcircle with all supported cards and also the
 *   PCMCIA cards (now patch for pcmcia-cs-3.0.13 needed) done.
 *
 * Revision 1.2  1999/06/21 15:24:26  calle
 * extend information in /proc.
 *
 * Revision 1.1  1997/03/04 21:27:33  calle
 * First version in isdn4linux
 *
 * Revision 2.2  1997/02/12 09:31:39  calle
 * new version
 *
 * Revision 1.1  1997/01/31 10:32:20  calle
 * Initial revision
