+* The ABI changes are planned for struct rte_intr_handle, struct rte_eth_conf

+  The upcoming release 2.1 will not contain these ABI changes by default.
+  This change will be in release 2.2. There's no backwards compatibility planed
+  due to the additional interrupt mode feature enabling.
+  Binaries using this library build prior to version 2.2 will require updating
+  and recompilation.
