Gowrishankar,

I still get this error with the v3 patches. My OS is Ubuntu 16.04 LTS
ppc64le. GCC version: Ubuntu/IBM 5.3.1-14ubuntu2
Can you help to check again?

ppc64le

Hi Chao,
I did not face this error. Even I verified today with tip of master
6596554... .
However I had patch conflict for examples/l3fwd/l3fwd_em.c which is fixed
now and v3 patch set sent recently. Could you please check.

Thanks,
Gowrishankar
