Hi all,
Finally Janek pointed me in the right direction: nictools-pci package
and the pci-config command
I tried the pre-down directive in the /etc/network/interfaces and it
worked ok but the second or third time I rebooted my PC it got frozen
so I started to search the internet and I found a web [1] explaining
how to use the pci-config
I've make it work using the following procedure:
lspci -nn |grep -i Ether
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev
01)
^^ The 2 digit at the beginning of the line means the pci bus (As
explained by Janek)
^ ^ this is the vendor:model number
Then:
pci-config -B 2
pci-config.c:v2.05 2/23/2005 Donald Becker (becker@scyld.com)
http://www.scyld.com/diag/index.html
Device #1 at bus 2 device/function 0/0, 816810ec.
^-----^ this
is tne model:vendor number the same as before BUT in different order
Now I know the BUS number (2) and device number (#1)
So I can use the pci-config to put the NIC in the proper state for WOL:
pci-config -B 2 -# 1 -S
Instead of using the pre-down directive in the /etc/network/interfaces
I choose the /etc/init.d/halt script as written in [1] and added the
following lines just before "halt -d -f $netdown $poweroff $hddown"

rmmod r8168

halt -d -f $netdown $poweroff $hddown
[...]
I have restarted my PC at least 10 times and it works without problem.
