-** HP CASCADE Architecture Driver for 100VG-AnyLan Network Adapters
-**
-** $Id: hp100.c,v 1.52 1997/04/21 14:20:20 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@jcu.cz>
-**
-** This driver has only been tested with
-** -- HP J2585B 10/100 Mbit/s PCI Busmaster
-** -- HP J2585A 10/100 Mbit/s PCI
-** -- HP J2970 10 Mbit/s PCI Combo 10base-T/BNC
-** -- HP J2973 10 Mbit/s PCI 10base-T
-** -- HP J2573 10/100 ISA
-** -- Compex ReadyLink ENET100-VG4 10/100 Mbit/s PCI / EISA
-**
-** 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.
