[dpdk-dev] [PATCH v4] KNI: use a memzone pool for KNI alloc/release

[Zhang, Helin]

> This patch implements the KNI memzone pool in order to prevent memzone
> exhaustion when allocating/deallocating KNI interfaces.
> 
> It adds a new API call, rte_kni_init(max_kni_ifaces) that shall be called before
> any call to rte_kni_alloc() if KNI is used.
> 
> v2: Moved KNI fd opening to rte_kni_init(). Revised style.
> v3: Adapted kni examples/tests to rte_kni_init().
> v4: Improved example integration. Fixed kni_memzone_pool_alloc/release()
> bug.
