OK, I checked the code in 4.8-RELEASE and only found polling in nge.
Interrupts I know. I'm trying to answer emails while my 2,5 year
daughter is playing with her Brio railroad and my 7 months son
is assisting her. Interrupts are almost using up 100% of my time.
I've googled and Marc'd quite a bit but I couldn't find any code in
the Gig drivers to put the pieces together.
