Hi Thiago,

As a reference, I tested spec file on Fedora 23, compilation worked fine.
Only I found you need to set RTE_TARGET=3Dx86_64-default-linuxapp-gcc
before building, to be able to package all files.

meanwhile PCI_MSIX_ENTRY_CTRL_MASKBIT is defined for kernels >=3D 2.6.38,
BUT it already defined in igb_uio/compat.h for the case kernel headers
don't have it, so it is not related to the kernel versions, not sure
about source of the error.

Thanks,
ferruh
