[dpdk-dev] Building current 1.8.1-rc1 with clang

[Wiles, Roger Keith]

I just pulled the current repo and stated a build with ‘make install T=x86_64-native-linuxapp-clang’ which produced the following error. I do not think I am allowed to modify this file, correct? If that is the case then someone will have to update the original source. If you want me to submit a patch I can, but I do not think I fully understand what needs to be done. 

>From what I can tell the line:
	dma_addr0 = _mm_xor_si128(dma_addr0, dma_addr0);
needs to be:
	dma_addr0 = _mm_setzero_si128();
