The physical addresses will be re-mapped into the kernel address space and stored in separate KNI contexts.
-Once KNI interfaces are created, the KNI context information can be queried by calling the rte_kni_info_get() function.
-
The KNI interfaces can be deleted by a DPDK application dynamically after being created.
Furthermore, all those KNI interfaces not deleted will be deleted on the release operation
of the miscellaneous device (when the DPDK application is closed).
