Hi Thomas, This patch is working for resolving the problem I found on RHEL6.5: http://dpdk.org/ml/archives/dev/2014-December/009827.html Because the root cause is socket struct change from 2.6.35, so this patch also fits for all kernels older than 2.6.35. Sorry for the ambiguous description, I think the title should be: "kni: more compatibility for kernel older than 2.6.35" Regards, Jincheng Miao > > Thanks
