Bugzilla Bug 113880

I figured out how to get WOL support working nicely with Gentoo, but it
requires
a  change to the net.ethX script to _not_ bring down the driver and network
card.  A configuration option would be useful to designate which NIC not to
bring down and also run: 

ethtool -s ethX wol g
(g being a magic packet, but it could be configurable, "pumbagsd" are all valid
options to ethtool)

Another requirement is that /etc/init.d/shutdown.sh needs the 'i' removed from
the a halt command to prevent the network cards from automatically being
shutdown by halt.

Comments?

lets get wol into the netscripts before we worry about using -i ;)

I'm not too sure about integrating ethtool myself - all it's commands would be
very system specific, so you might as well do this in /etc/conf.d/net

down_eth0="no" # unimplented, but trivial if required
postdown() {
   # Enable WOL for eth0
   if [[ ${IFACE} == "eth0" ]]; then
      ethtool -s "${IFACE}" wol g
   fi
}

We could always document that in /etc/conf.d/net.example

OR we could do this

down_eth0="no" # unimplented, but trivial if required
ethtool_eth0="wol g"

Easier to configure perhaps, but with the added weight of another module

Thoughts?

I think the postdown() and down_ethX is much cleaner, and could be more useful.
 All that is really required by the net scripts is not bringing down the
interface.  Add a comment in the postdown() method regarding WOL and we should
be done.

Wake On LAN patch

This patch adds an example in the postdown function for WOL and adds the
RC_DOWN_INTERFACE variable to /etc/conf.d/rc which is used by net.lo and
shutdown.sh

Wanna test it against baselayout-1.12.0_pre11-r3 ?

Right, 2 people have added themselves to this bug - could either they or the 
reporter please give some indication whether this patch enables a working WOL 
or not. 

I shall try it out

It worked fine for me.  I tested with the AMD magic packet tool for windows.

Applied to our SVN repo - will be in baselayout-1.12.0_pre13

.

It worked for me too :), thanks.

But instead of using postdown() suggested on the patch, I've used the one from
comment #2, because ethtool complains if you try to activate WOL for "lo" ;)

BTW,for enabling WoL I used to add the "ethtool -s ethX wol g" at
/etc/conf.d/local.stop but it stopped working. Does anyone knowns the reason?

OK, example updated to this

[[ ${IFACE} != "lo" ]] && ethtool -s "${IFACE}" wol g

local gets stopped before net.eth0 - so WOL gets applied by local and then
forgotten as net.eth0 takes the interface down.

Just a guess .....

Fixed in pre13

Please consider the following comment:

3c59x cards don't appear to work well with ethtool:
# ethtool -s eth0 wol g
Cannot get current wake-on-lan settings: Operation not supported
  not setting wol

On the other hand, when I use ifconfig eth0 down, I am able to put the adapter
in D3 mode (the mode where I can wake up from lan). See this:

BEFORE:
00:0f.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78)
  ...
  Status: D0 PME-Enable- DSel=0 DScale=2 PME-

# ifconfig eth0 down

00:0f.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78)
  ...
  Status: D3 PME-Enable- DSel=0 DScale=2 PME-

Please make sure we can pick either ethtool or ifconfig to put the ethernet
card in WOL mode. Thanks.

Great !

This new baselayout release allowed me to make wol work. ASUS A8NSLI / skge
module. Just had to add ethtool -s eth0 wol g to /etc/conf.d/local.stop

Thanks !
