/*
* 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] http://www.openflow.org/documents/openflow-spec-v1.0.0.pdf

* 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

* 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.
