Subject: SunHME: trying to enable netconsole/netpolling

Hi David

Can you please advice
I am a newbie here.
I am trying to enable netconsole output with sunhme card,
I found that poll_controller is not defined and defined it
as it is defined in other drivers (just to watch if it will work, I
dont understand this code yet)
My patch is in attach.
My card is connected to PCI bus.

netconsole is working now!
(and network is  still working too)
but I get the following warning:
