/* 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 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'   
   
   *    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 !
