It's a bit more code and probably overkill as a solution to this particular problem, but hopefully it'll make it easier to add new VFIO drivers down the line (with each driver having their own DMA mapping function), should we choose to do so. I'm still working on the patch, but if everyone is OK with this approach instead of a more general one, that's fine with me.

Hi Anatoly,
This patch sent just to show what changes done to test VFIO no-iommu I mentioned,
and to have a justification for the kernel patch, not sent as a final solution in DPDK,
sorry for interrupting your work.
Thanks,
ferruh
