+Jumbo: Limitation
+-----------------
+
+Rx descriptor limit for number of segments per MTU is set to 1.
+PMD doesn't support Jumbo Rx scatter gather. Some applciations can
+adjust mbuf_size based on this param and max_pkt_len.
+
+For others, PMD detects the condition where Rx packet length cannot
+be held by configured mbuf size and logs the message.
