* $Log: nic3008.c,v $
|
|
* Revision 1.14 1995/12/17 21:14:34 phk
|
|
* Staticize.
|
|
*
|
|
* Revision 1.13 1995/12/08 23:19:29 phk
|
|
* Julian forgot to make the *devsw structures static.
|
|
*
|
|
* Revision 1.12 1995/12/08 11:12:45 julian
|
|
* Pass 3 of the great devsw changes
|
|
* most devsw referenced functions are now static, as they are
|
|
* in the same file as their devsw structure. I've also added DEVFS
|
|
* support for nearly every device in the system, however
|
|
* many of the devices have 'incorrect' names under DEVFS
|
|
* because I couldn't quickly work out the correct naming conventions.
|
|
* (but devfs won't be coming on line for a month or so anyhow so that doesn't
|
|
* matter)
|
|
*
|
|
* If you "OWN" a device which would normally have an entry in /dev
|
|
* then search for the devfs_add_devsw() entries and munge to make them right..
|
|
* check out similar devices to see what I might have done in them in you
|
|
* can't see what's going on..
|
|
* for a laugh compare conf.c conf.h defore and after... :)
|
|
* I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
|
|
* a much more complicated job.. (pass 5 :)
|
|
*
|
|
* pass 4 will be to make the devsw tables of type (cdevsw * )
|
|
* rather than (cdevsw)
|
|
* seems to work here..
|
|
* complaints to the usual places.. :)
|
|
*
|
|
* Revision 1.11 1995/11/29 14:39:07 julian
|
|
* If you're going to mechanically replicate something in 50 files
|
|
* it's best to not have a (compiles cleanly) typo in it! (sigh)
|
|
*
|
|
* Revision 1.10 1995/11/29 10:47:04 julian
|
|
* OK, that's it..
|
|
* That's EVERY SINGLE driver that has an entry in conf.c..
|
|
* my next trick will be to define cdevsw[] and bdevsw[]
|
|
* as empty arrays and remove all those DAMNED defines as well..
|
|
*
|
|
* Revision 1.9 1995/11/21 14:56:01 bde
|
|
* Completed function declarations, added prototypes and removed redundant
|
|
* declarations.
|
|
*
|
|
* Revision 1.8 1995/11/18 04:19:44 bde
|
|
* Fixed the type of nic_listen(). A trailing arg was missing.
|
|
*
|
|
* Fixed calls to s_intr(). There was sometimes an extra trailing arg.
|
|
*
|
|
* Revision 1.7 1995/09/08 11:06:46 bde
|
|
* Fix benign type mismatches in devsw functions. 82 out of 299 devsw
|
|
* functions were wrong.
|
|
*
|
|
* Revision 1.6 1995/05/30 07:57:57 rgrimes
|
|
* Remove trailing whitespace.
|
|
*
|
|
* Revision 1.5 1995/05/11 19:25:55 rgrimes
|
|
* Fix -Wformat warnings from LINT kernel.
|
|
*
|
|
* Revision 1.4 1995/03/28 07:54:31 bde
|
|
* Add and move declarations to fix all of the warnings from `gcc -Wimplicit'
|
|
* (except in netccitt, netiso and netns) that I didn't notice when I fixed
|
|
* "all" such warnings before.
|
|
*
|
|
* Revision 1.3 1995/03/19 14:28:35 davidg
|
|
* Removed redundant newlines that were in some panic strings.
|
|
*
|
|
* Revision 1.2 1995/02/15 11:59:40 jkh
|
|
* Fix a few more nits. Should compile better now! :_)
|
|
*
|
|
* Revision 1.1 1995/02/14 15:00:10 jkh
|
|
* An ISDN driver that supports the EDSS1 and the 1TR6 ISDN interfaces.
|
|
* EDSS1 is the "Euro-ISDN", 1TR6 is the soon obsolete german ISDN Interface.
|
|
* Obtained from: Dietmar Friede <dfriede@drnhh.neuhaus.de> and
|
|
* Juergen Krause <jkr@saarlink.de>
|
|
*
|
|
* This is only one part - the rest to follow in a couple of hours.
|
|
* This part is a benign import, since it doesn't affect anything else.
