Fixed it by manually defining it for older kernels. Reported-by: Xu, Qian Q Signed-off-by: Marcel Apfelbaum --- Hi, I reproduced the issue with 3.9.5 kernel and solved using Xie, Huawei's idea. By the way, what is the earlier kernel that DPDK supports? I tried 3.19 with no luck. Please let me know if you prefer another way to do it.
