3	** HP CASCADE Architecture Driver for 100VG-AnyLan Network Adapters
4	**
5	** $Id: hp100.c,v 1.1.4.1 2005/06/02 18:52:39 ams Exp $
6	**
7	** Based on the HP100 driver written by Jaroslav Kysela <perex@jcu.cz>
8	** Extended for new busmaster capable chipsets by
9	** Siegfried "Frieder" Loeffler (dg1sek) <floeff@mathematik.uni-stuttgart.de>
10	**
11	** Maintained by: Jaroslav Kysela <perex@jcu.cz>
12	**
13	** This driver has only been tested with
14	** -- HP J2585B 10/100 Mbit/s PCI Busmaster
15	** -- HP J2585A 10/100 Mbit/s PCI
16	** -- HP J2970 10 Mbit/s PCI Combo 10base-T/BNC
17	** -- HP J2973 10 Mbit/s PCI 10base-T
18	** -- HP J2573 10/100 ISA
19	** -- Compex ReadyLink ENET100-VG4 10/100 Mbit/s PCI / EISA
20	** -- Compex FreedomLine 100/VG 10/100 Mbit/s ISA / EISA / PCI
21	**
22	** but it should also work with the other CASCADE based adapters.
23	**
24	** TODO:
25	** - J2573 seems to hang sometimes when in shared memory mode.
26	** - Mode for Priority TX
27	** - Check PCI registers, performance might be improved?
28	** - To reduce interrupt load in busmaster, one could switch off
29	** the interrupts that are used to refill the queues whenever the
30	** queues are filled up to more than a certain threshold.
31	** - some updates for EISA version of card
32	**
33	**
34	** This source/code is public free; you can distribute it and/or modify
35	** it under terms of the GNU General Public License (published by the
36	** Free Software Foundation) either version two of this License, or any
37	** later version.
38	**
39	** 1.55 -> 1.56
40	** - removed printk in misc. interrupt and update statistics to allow
41	** monitoring of card status
42	** - timing changes in xmit routines, relogin to 100VG hub added when
43	** driver does reset
44	** - included fix for Compex FreedomLine PCI adapter
45	**
46	** 1.54 -> 1.55
47	** - fixed bad initialization in init_module
48	** - added Compex FreedomLine adapter
49	** - some fixes in card initialization
50	**
51	** 1.53 -> 1.54
52	** - added hardware multicast filter support (doesn't work)
53	** - little changes in hp100_sense_lan routine
54	** - added support for Coax and AUI (J2970)
55	** - fix for multiple cards and hp100_mode parameter (insmod)
56	** - fix for shared IRQ
57	**
58	** 1.52 -> 1.53
59	** - fixed bug in multicast support
