* The following fields have been deprecated in rte_eth_stats:
imissed, ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
+
+* API for flow director filters has been replaced by rte_eth_dev_filter_ctrl.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 change is planned to extend the SCTP flow's key input from release 2.1.
+ The change may be enabled in the release 2.1 with CONFIG_RTE_NEXT_ABI.
+
+* 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.
+
+* 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.
+
+* The scheduler statistics structure will change to allow keeping track of
+ RED actions.
