            Bug ID: 998
           Summary: kni: corruption when using incompatible version of
                    rte_kni.ko
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org

dmesg for one BUG it caused

KNI ioctl functions copy data from userspace lib, and this interface of kmod is
not compatible indeed. If the user use incompatible rte_kni.ko, corruption is
detected in struct rte_kni_device_info. 

It could cause a BUG in librte_kni.ko and there's no measure to restore kni
function without reboot. The related EAL thread also vanishes.
