-/* ne2.c: A NE/2 Ethernet Driver for Linux. */
-/*
- Based on the NE2000 driver written by Donald Becker (1992-94).
- modified by Wim Dumon (Apr 1996)
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- The author may be reached as wimpie@linux.cc.kuleuven.ac.be
-
- Currently supported: NE/2
- This patch was never tested on other MCA-ethernet adapters, but it
- might work. Just give it a try and let me know if you have problems.
- Also mail me if it really works, please!
-
- Changelog:
- Mon Feb 3 16:26:02 MET 1997
- - adapted the driver to work with the 2.1.25 kernel
- - multiple ne2 support (untested)
- - module support (untested)
-
- Fri Aug 28 00:18:36 CET 1998 (David Weinehall)
- - fixed a few minor typos
- - made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
- - fixed the module support (Now it's working...)
-
- Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
- - added support for Arco Electronics AE/2-card (experimental)
-
- Mon Sep 14 09:53:42 CET 1998 (David Weinehall)
- - added support for Compex ENET-16MC/P (experimental)
-
- Tue Sep 15 16:21:12 CET 1998 (David Weinehall, Magnus Jonsson, Tomas Ogren)
- - Miscellaneous bugfixes
-
- Tue Sep 19 16:21:12 CET 1998 (Magnus Jonsson)
- - Cleanup
-
- Wed Sep 23 14:33:34 CET 1998 (David Weinehall)
- - Restructuring and rewriting for v2.1.x compliance
-
- Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
- - Added code that unregisters irq and proc-info
- - Version# bump
-
- Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
- - pass 'dev' as last parameter of request_irq in stead of 'NULL'
-
- Wed Feb 7 21:24:00 CET 2001 (Alfred Arnold)
- - added support for the D-Link DE-320CT
-
- * WARNING
- -------
- This is alpha-test software. It is not guaranteed to work. As a
- matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
- would like to hear from you if you use this driver, even if it works.
- If it doesn't work, be sure to send me a mail with the problems !
