 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 The Latency stats library marks the time in the timestamp field of the
-mbuf for the ingress packets and sets the ``PKT_RX_TIMESTAMP`` flag of
+mbuf for the ingress packets and sets the ``RTE_MBUF_F_RX_TIMESTAMP`` flag of
 ``ol_flags`` for the mbuf to indicate the marked time as a valid one.
 At the egress, the mbufs with the flag set are considered having valid
 timestamp and are used for the latency calculation.
