+ *
+ * Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
+ *
+ * $Log: avmcard.h,v $
+ * Revision 1.4 1999/08/04 10:10:08 calle
+ * Bugfix: corrected /proc functions, added structure for new AVM cards.
+ *
+ * Revision 1.3 1999/07/23 08:41:47 calle
+ * prepared for new AVM cards.
+ *
+ * Revision 1.2 1999/07/05 15:09:45 calle
+ * - renamed "appl_release" to "appl_released".
+ * - version und profile data now cleared on controller reset
+ * - extended /proc interface, to allow driver and controller specific
+ * informations to include by driver hackers.
+ *
+ * Revision 1.1 1999/07/01 15:26:22 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.
