tg3 driver does not support S4 mode?

tg3 driver does not support S4 mode?

[John Knottenbelt]

Hi

I'm running Linux 2.6.0:

On entering S4 I get:

tg3: eth0: Invalid power state (4) requested.

Relevant kernel messages follow below. How hard
do you think it would be to add S4 support for 
tg3. What does S4 support involve?

Many thanks

John

Maybe we should be calling device_suspend(*3*) from swsusp.c, because
we want devices to enter D3 state (and they dont care about us
entering S*4*)...

[Patrick, could you comment on that? It is not obvious from quick scan
of documentation].
