I see. After looking at the code it seems like sglist will coalesce contiguous physical ranges without taking page boundaries into account, which is not suitable for our purpose here. I guess I will either have to modify sglist, or switch to using bus_dma. The main problem with using bus_dma is that it will require bigger changes to netfront I think. Thanks, Roger.
