-* API for flow director filters has been replaced by rte_eth_dev_filter_ctrl.
- Following old API is deprecated and will be removed with version 2.2 without
- backward compatibility.
- Functions: rte_eth_dev_fdir_*.
- Structures: rte_fdir_*, rte_eth_fdir.
- Enums: rte_l4type, rte_iptype.
-
-* ABI changes are planned for struct rte_eth_fdir_flow_ext in order to support
- flow director filtering in VF. The release 2.1 does not contain these ABI
- changes, but release 2.2 will, and no backwards compatibility is planned.
-
-* ABI changes are planned for struct rte_eth_fdir_filter and
- rte_eth_fdir_masks in order to support new flow director modes,
- MAC VLAN and Cloud, on x550. The MAC VLAN mode means the MAC and
- VLAN are monitored. The Cloud mode is for VxLAN and NVGRE, and
- 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.
-
-* ABI changes are planned for struct virtio_net in order to support vhost-user
- multiple queues feature.
- It should be integrated in release 2.2 without backward compatibility.
-
-* The scheduler hierarchy structure (rte_sched_port_hierarchy) will change to
- allow for a larger number of subport entries.
- The number of available traffic_classes and queues may also change.
- The mbuf structure element for sched hierarchy will also change from a single
- 32 bit to a 64 bit structure.
