capability first, if it's a invalid port we'll get a prompt saying

Please reconsider your interpretation of the word "debuggability". Debugging is
not only something that R&D staff does in a lab. Debuggability can also be

This commit is adding a generic mechanism to support multiple IOMMU
types. For now, it's only type 1 (x86 IOMMU) and no-IOMMU (a special
VFIO mode that doesn't use IOMMU at all), but it's easily extended
by adding necessary definitions into eal_pci_init.h and a DMA
mapping function to eal_pci_vfio_
