The other stuff has been deleted. Windows does not have sys/queue.h, so we reproduce it here. Would it better to have this as a dependency outside of DPDK? I think pulling a file from the internet and applying a patch (where we'd have to maintain a patch file inside of DPDK's repo anyway) would be overkill when we just need a few lines of code that will change very infrequently.
