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).
the tunnel type, TNI/VNI, inner MAC and inner VLAN are monitored.
The release 2.2 will contain these changes without backwards compatibility.
-* librte_kni: Functions based on port id are deprecated for a long time and
- should be removed (rte_kni_create, rte_kni_get_port_id and rte_kni_info_get).
-
* librte_pmd_ring: The deprecated functions rte_eth_ring_pair_create and
rte_eth_ring_pair_attach should be removed.
* The deprecated ACL API ipv4vlan is removed.
+* The deprecated KNI functions are removed:
+ rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().

In addition, one or more kernel NIC interfaces are allocated for each
of the configured ports according to the command line parameters.
-The code for creating the kernel NIC interface for a specific port is as follows:
-
-.. code-block:: c
-
- kni = rte_kni_create(port, MAX_PACKET_SZ, pktmbuf_pool, &kni_ops);
- if (kni == NULL)
- rte_exit(EXIT_FAILURE, "Fail to create kni dev "
- "for port: %d\n", port);
-
The code for allocating the kernel NIC interfaces for a specific port is as follows:
.. code-block:: c

-LIBABIVER := 1
+LIBABIVER := 2
# all source are stored in SRCS-y
