Hi Thomas,

> I wonder if we could replace igb_uio by uio_pci_generic?

Can it do DMA or IOMMU support? Not even VFIO does everything we need, you =
may have noticed that I have to go to PCI config space to enable bus master=
ing. I don't think that driver can do either of those things. Unless, of co=
urse, you meant simply not tying the binding script to specific driver, whi=
ch in effect is already in place (although it does check whether vfio-pci o=
r igb_uio are loaded).

Best regards,
Anatoly Burakov
