[dpdk-stable] [dpdk-dev] [PATCH] examples/kni: fix crash while handling userspace request

[Thomas Monjalon]

> > Meanwhile sample application continues to read from KNI interface queues and
> > push into device queues. This simultaneous access may cause a crash, crash log
> > can be found at defect description.

> > As a solution KNI sample application can do the proper synchronization, and
> > stop transfer between KNI interface and physical interface while physical device
> > stop/started.
