+ * This module implements decoding of OpenFlow protocol version 1.0 (wire
+ * protocol 0x01). The decoder implements terse (default), detailed (-v) and
+ * full (-vv) output formats and, as much as each format implies, detects and
+ * tries to work around sizing anomalies inside the messages. The decoder marks
+ * up bogus values of selected message fields and decodes partially captured
+ * messages up to the snapshot end. It is based on the specification below:
+ *
+ * [OF10] https://www.opennetworking.org/wp-content/uploads/2013/04/openflow-spec-v1.0.0.pdf
+ *
+ * Most functions in this file take the following arguments:
+ * * cp -- the pointer to the first octet to decode
+ * * len -- the declared length of the structure to decode
+ * The convention is that a printer function returns iff the given structure is
+ * completely within the packet buffer; otherwise it processes the part that is
+ * within the buffer, sooner of later takes the "truncated packet" shortcut via
+ * longjmp() and never returns. With that in mind, the function may return
+ * without printing the structure completely if it is invalid or the ndo_vflag
+ * value is not high enough. This way the calling function can try to decode
+ * the next data item.
+ *
+ * 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.
+ *
+ * Partial decoding of Big Switch Networks vendor extensions is done after the
+ * oftest (OpenFlow Testing Framework) and Loxigen (library generator) source
+ * code.
