Hi Thomas, I made the required change in order to support the 82541GI chipset and I was able to bind it successfully to the igb_uio ==> thank for your advise. however i am stll not able to bind the 82575EB... although it looks like it is already supported ;(
I see there is a 82575EB_COPPER and a 82575EB_FIBER_SERDES, how can i tell if mine is one of them? it is a Dual Port PCI-E X4 Gigabit Server Adapter 575T ( http://www.winyao.com/en/product_view_20_117.html).
