Hello e1000e developers,
I have a problem getting a specific wake-on-lan combination getting to
work on my onboard 82574L PCIe adapter. I would like to wake the system
from S3 by either an ARP request or an unicast packet send to the system,
e.g. an ICMP packet. What I'm seeing is that wake-on-unicast works, but
wake-on-arp does not, albeit the adapter is configured to do so:
root@puck:~# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
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 pause frame use: No
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
MDI-X: off
Supports Wake-on: pumbag
Wake-on: uag
Current message level: 0x00000001 (1)
Link detected: yes
"g" is included in the wake-on list to work around the problem and have a
way to wakeup the system by sending a magic packet. But what I really want
is to skip this manual step and let the machine wakeup automatically when
someone wants to access it.
Reading the specification (document number 317694-020, section 5.5.3.1),
the adapter should wake on ARP request because it wakes up on unicast
packets directed to the configured IPv4 address. The document states that
the ARP method and the unicast method are using the same table for IP
addresses matching (IP4AT), so if it works for the unicast case it should
work for the ARP case also, shouldn't it?
Any idea why it doesn't work?
I'm running 2.6.37.1. Here is the lspci for completeness:

P.S.: No, it's not possible to add a static ARP entry on every possible
machine accessing it, so only unicast packets would be generated.
