dpdk installation error

[choleraehyq]

Error occured when I was compiling dpdk using dpdk/tools/dpdk-setup.sh, both with x86_64-native-linuxapp-gcc and x86_64-native-linuxapp-clang.

I can successfully compile DPDK 17.05, but I don't know which version of DPDK does f-stack use.

[choleraehyq]

I've updated DPDK to 17.05, and fixed for some compatible issues. DPDK and f-stack can be successfully compiled, but redis is still broken.

I think the reason is that in linux the header containing struct timespec is time.h, but in freebsd is sys/time.h. In redis compilation we haven't overriden the include root to freebsd root. So struct timespec haven't been imported into ae_ff_kqueue.c.

The version of dpdk that f-stack use is 16.07. And we didn't test it with gcc 5+.
The redis error is that we push the codes to github with permission loss.
