Submitting just the PMD for integration makes sense. I will remove all the
references to nfp_uio.

My doubt is with documentation. Working with the NFP PMD will not be
possible without nfp_uio. We could modify the documentation saying it is
possible to use igb_uio, but this is not the right thing to do (pci mask
will be wrong). So, would it be acceptable to submit a new PMD without any
documentation by now? I prefer this for the sake of integration than giving
wrong or incomplete documentation.

Thanks
