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 |
