-** HP CASCADE Architecture Driver for 100VG-AnyLan Network Adapters
-**
-** $Id: hp100.c,v 1.58 2001/09/24 18:03:01 perex Exp perex $
-**
-** Based on the HP100 driver written by Jaroslav Kysela <perex@jcu.cz>
-** Extended for new busmaster capable chipsets by
-** Siegfried "Frieder" Loeffler (dg1sek) <floeff@mathematik.uni-stuttgart.de>
-**
-** Maintained by: Jaroslav Kysela <perex@perex.cz>
-**
-** This driver has only been tested with
-** -- HP J2585B 10/100 Mbit/s PCI Busmaster
-** -- HP J2585A 10/100 Mbit/s PCI
-** -- HP J2970A 10 Mbit/s PCI Combo 10base-T/BNC
-** -- HP J2973A 10 Mbit/s PCI 10base-T
-** -- HP J2573 10/100 ISA
-** -- Compex ReadyLink ENET100-VG4 10/100 Mbit/s PCI / EISA
-** -- Compex FreedomLine 100/VG 10/100 Mbit/s ISA / EISA / PCI
-**
-** but it should also work with the other CASCADE based adapters.
-**
-** TODO:
-** - J2573 seems to hang sometimes when in shared memory mode.
-** - Mode for Priority TX
-** - Check PCI registers, performance might be improved?
-** - To reduce interrupt load in busmaster, one could switch off
-** the interrupts that are used to refill the queues whenever the
-** queues are filled up to more than a certain threshold.
-** - some updates for EISA version of card
-**
-**
-**
-** 1.57c -> 1.58
-** - used indent to change coding-style
-** - added KTI DP-200 EISA ID
-** - ioremap is also used for low (<1MB) memory (multi-architecture support)
-**
-** 1.57b -> 1.57c - Arnaldo Carvalho de Melo <acme@conectiva.com.br>
-** - release resources on failure in init_module
-**
-** 1.57 -> 1.57b - Jean II
-** - fix spinlocks, SMP is now working !
-**
-** 1.56 -> 1.57
-** - updates for new PCI interface for 2.1 kernels
-**
-** 1.55 -> 1.56
-** - removed printk in misc. interrupt and update statistics to allow
-** monitoring of card status
-** - timing changes in xmit routines, relogin to 100VG hub added when
-** driver does reset
-** - included fix for Compex FreedomLine PCI adapter
-**
-** 1.54 -> 1.55
-** - fixed bad initialization in init_module
-** - added Compex FreedomLine adapter
-** - some fixes in card initialization
-**
-** 1.53 -> 1.54
-** - added hardware multicast filter support (doesn't work)
-** - little changes in hp100_sense_lan routine
-** - added support for Coax and AUI (J2970)
-** - fix for multiple cards and hp100_mode parameter (insmod)
-** - fix for shared IRQ
-**
-** 1.52 -> 1.53
-** - fixed bug in multicast support
