+ * Most functions in this file take 3 arguments into account:
+ * * cp -- the pointer to the first octet to decode
+ * * len -- the length of the current structure as declared on the wire
+ * * ep -- the pointer to the end of the captured frame
+ * They return either the pointer to the next not-yet-decoded part of the frame
+ * or the value of ep, which means the current frame processing is over as it
+ * has been fully decoded or is invalid or truncated. This way it is possible
+ * to chain and nest such functions uniformly to decode an OF1.0 message, which
+ * consists of several layers of nested structures.
+ *
* 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
* tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of
* the nested frames.
*
+ * Partial decoding of Big Switch Networks vendor extensions is done after the
+ * oftest (OpenFlow Testing Framework) and Loxigen (library generator) source
+ * code.
