2 * This module implements decoding of OpenFlow protocol version 1.0 (wire
3 * protocol 0x01). The decoder implements terse (default), detailed (-v) and
4 * full (-vv) output formats and, as much as each format implies, detects and
5 * tries to work around sizing anomalies inside the messages. The decoder marks
6 * up bogus values of selected message fields and decodes partially captured
7 * messages up to the snapshot end. It is based on the specification below:
9 * [OF10] http://www.openflow.org/documents/openflow-spec-v1.0.0.pdf
11 * Most functions in this file take 3 arguments into account:
12 * * cp -- the pointer to the first octet to decode
13 * * len -- the length of the current structure as declared on the wire
14 * * ep -- the pointer to the end of the captured frame
15 * They return either the pointer to the next not-yet-decoded part of the frame
16 * or the value of ep, which means the current frame processing is over as it
17 * has been fully decoded or is invalid or truncated. This way it is possible
18 * to chain and nest such functions uniformly to decode an OF1.0 message, which
19 * consists of several layers of nested structures.
21 * Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT
22 * messages is done only when the verbosity level set by command-line argument
23 * is "-vvv" or higher. In that case the verbosity level is temporarily
24 * decremented by 3 during the nested frame decoding. For example, running
25 * tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of
28 * Partial decoding of Big Switch Networks vendor extensions is done after the
29 * oftest (OpenFlow Testing Framework) and Loxigen (library generator) source
