| 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: |
| 8 | * |
| 9 | * [OF10] http://www.openflow.org/documents/openflow-spec-v1.0.0.pdf |
| 10 | * |
| 11 | * Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT |
| 12 | * messages is done only when the verbosity level set by command-line argument |
| 13 | * is "-vvv" or higher. In that case the verbosity level is temporarily |
| 14 | * decremented by 3 during the nested frame decoding. For example, running |
| 15 | * tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of |
| 16 | * the nested frames. |
