It aims at solving alignment issues between the build system and the system applications linked ot DPDK libraries are run on. It can also help simplify spaghetti code done to support different versions of the Linux Kernel headers used by the build system. Guidelines and import script are also part of first patch. Follow-up patches are an example of imported uAPI inclusion of VDUSE header into the Vhost library.
