Hi all,

this series lifts the somewhat hacky checks in the XSK code if a DMA
streaming mapping needs dma_sync_single_for_{device,cpu} calls to the
DMA API.
Thanks a lot for working on, and fixing this, Christoph!

I took the series for a spin, and there are (obviously) no performance
regressions.

Would the patches go through the net/bpf trees or somewhere else?
either the net tree or (my) dma-mapping tree would be fine with me.
