Hi to LKML,

I'm experiencing some troubles with WOL with my nForce NIC.
The problem is simple - after setting WOL mode to magic packet my PC
won't wake up. I've noticed there were some changes about this in new
kernel, but no luck for me.

I'm using 2.6.18 kernel, vanilla. I've tried this with Windows Vista RC1
(build 5600) and WOL works correctly. My NIC is integrated on MSI K8N
Neo4-FI

Is there any way how can I help with developement of this feature?

On my nForce4 CK804 it's disabled by default, I bet this is your problem:

[root] 19:33 [~] ethtool lan
Settings for lan:
Supported ports: [ MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 1
Transceiver: external
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Link detected: yes

Read the manpage for ethtool. HTH.

Did you check that WOL was enabled? I need to re-activate it after each
boot (I guess that's normal, not sure though).
The output of "ethtool eth0" should show:

Supports Wake-on: g
Wake-on: g

Also, I remember a bugzilla entry in which it was said that the MAC was
somehow reversed by the driver. I that is still the case (I can't find
the bugzilla entry right now), you might just reverse the MAC address in
your WOL packet to workaround the bug.
