Ok, I ignore these warning as reference to current release code. More clean code
will been sent in future.

Ok. I don't know this before. :), thank you.

Sorry for causing misleading understanding,
Glibc memset() use vectorization instructions to implement optimization, of course.
I just want to say "the functions for implementing the same functionality
like glibc memset() ". My bad English expressions. :)

I can run command line "memset_autotest", It seems that I leave something out.

Ok.
Maybe memset() consumes small ratio for current DPDK data path.

I'm not familiar with glibc regulation, as far as I know, glibc is using X86 asm,
rather than intrinsic. I will consider your suggestion.
