1 /* ne2.c: A NE/2 Ethernet Driver for Linux. */
3 Based on the NE2000 driver written by Donald Becker (1992-94).
4 modified by Wim Dumon (Apr 1996)

11 Currently supported: NE/2
12 This patch was never tested on other MCA-ethernet adapters, but it
13 might work. Just give it a try and let me know if you have problems.
14 Also mail me if it really works, please!
17 Mon Feb 3 16:26:02 MET 1997
18 - adapted the driver to work with the 2.1.25 kernel
19 - multiple ne2 support (untested)
20 - module support (untested)
22 Fri Aug 28 00:18:36 CET 1998 (David Weinehall)
23 - fixed a few minor typos
24 - made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
25 - fixed the module support (Now it's working...)
27 Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
28 - added support for Arco Electronics AE/2-card (experimental)
30 Mon Sep 14 09:53:42 CET 1998 (David Weinehall)
31 - added support for Compex ENET-16MC/P (experimental)
33 Tue Sep 15 16:21:12 CET 1998 (David Weinehall, Magnus Jonsson, Tomas Ogren)
34 - Miscellaneous bugfixes
36 Tue Sep 19 16:21:12 CET 1998 (Magnus Jonsson)
39 Wed Sep 23 14:33:34 CET 1998 (David Weinehall)
40 - Restructuring and rewriting for v2.1.x compliance
42 Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
43 - Added code that unregisters irq and proc-info
46 Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
47 - pass 'dev' as last parameter of request_irq in stead of 'NULL'
51 This is alpha-test software. It is not guaranteed to work. As a
52 matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
53 would like to hear from you if you use this driver, even if it works.
54 If it doesn't work, be sure to send me a mail with the problems !
