Hi Thomas,

This patch is working for resolving the problem I found on RHEL6.5:

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"
