+* vhost: The vhost library currently populates received mbufs from a virtio
+  driver with Tx offload flags while not filling Rx offload flags.
+  While this behavior is arguable, it is kept untouched.
+  A new flag ``RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS`` has been added to ask

+  supports two additional parameters, ``status`` and ``num_unsuccessful``,
+  to allow the reporting of errors from hardware when performing copy
