Description of problem:
I have a dual-boot Linux/Windows machine with a SMC EtherPower II (EPIC/100
83c170) network card.  When rebooting from Windows, the Windows driver will
leave the card in the ACPI D3 state.

The epic100.o module that ships with Red Hat Linux 7.1 does not know how to
restore the ACPI power state of the card.  Therefore, if I have booted my
machine into Windows, in order to boot into Linux, I must first completely
power off my machine and power it back on.


How reproducible:
Always

Steps to Reproduce:
1.  Build a dual-boot Windows 98 / Red Hat Linux 7.1 system with a SMC
EtherPower II (EPIC/100 83c170) network card.
2.  Boot the system into Windows.
3.  From Windows, reboot into Linux.

Additional info:

I've already encountered this problem under RH7.0 (kernel 2.2):

http://www.scyld.com/pipermail/epic-bug/2000-November/000000.html

The way I resolved the problem then was to move to using Becker's network
driver updates:

http://www.scyld.com/network/updates.html

But I can't do this for RH7.1 (kernel 2.4) because he hasn't yet ported his
epic100 to the 2.4 kernel.  I need a epic100.c that both works for kernel
2.4 *and* knows how to restore the ACPI power state of the card.
