+ * Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT
+ * messages is done only when the verbosity level set by command-line argument
+ * is "-vvv" or higher. In that case the verbosity level is temporarily
+ * decremented by 3 during the nested frame decoding. For example, running
+ * tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of
+ * the nested frames.
