- * $Log: b1capi.c,v $
- * Revision 1.10 1998/02/13 07:09:10 calle
- * change for 2.1.86 (removing FREE_READ/FREE_WRITE from [dev]_kfree_skb()
- *
- * Revision 1.9 1998/01/31 11:14:39 calle
- * merged changes to 2.0 tree, prepare 2.1.82 to work.
- *
- * Revision 1.8 1997/12/10 20:00:46 calle
- * get changes from 2.0 version
- *
- * Revision 1.4.2.5 1997/12/07 19:59:54 calle

- *
- * Revision 1.7 1997/10/19 14:45:40 calle
- * fixed capi_get_version.
- *
- * Revision 1.6 1997/10/01 09:21:09 fritz
- * Removed old compatibility stuff for 2.0.X kernels.
- * From now on, this code is for 2.1.X ONLY!
- * Old stuff is still in the separate branch.
- *
- * Revision 1.5 1997/07/12 08:22:26 calle
- * Correct bug in CARD_NR macro, so now more than one card will work.
- * Allow card reset, even if card is in running state.
- *
- *
- * Revision 1.4 1997/05/27 15:17:45 fritz
- * Added changes for recent 2.1.x kernels:
- * changed return type of isdn_close
- * queue_task_* -> queue_task
- * clear/set_bit -> test_and_... where apropriate.
- * changed type of hard_header_cache parameter.
- *
- * Revision 1.3 1997/05/18 09:24:09 calle
- * added verbose disconnect reason reporting to avmb1.
- * some fixes in capi20 interface.
- * changed info messages for B1-PCI
- *
- * Revision 1.2 1997/03/05 21:20:41 fritz
