- * Dissector Notes:
- *
- * 1) SEL Fast Message protocol over TCP is normally tunneled via a Telnet connection. As Telnet
- * has special handling for the 0xFF character ("IAC"), normally a pair of 0xFF's are inserted
- * to represent an actual payload byte of 0xFF. A function from the packet-telnet.c dissector has
- * been borrowed to automatically pre-process any Ethernet-based packet and remove these 'extra'
- * 0xFF bytes. Wireshark Notes on Telnet 0xFF doubling are discussed here:
- * http://www.wireshark.org/lists/wireshark-bugs/201204/msg00198.html
- *
- * 2) As the presence of 0xFF pad bytes can render the "length" byte of a response message inaccurate
- * (as the 'length' does not compensate for these extra bytes) it can be difficult to accurately determine
- * the proper length of a message when attempting to do TCP reassembly. The get_selfm_len function
- * does a best-guess, based on evidence observed from multiple packet captures from different devices.
- * What would be ideal would be to:
- * a) Attempt initial PDU re-assembly based on length byte
- * b) Detect if a 0xFF pair is found in the payload and add 1 byte to the PDU length
- * c) Continue re-assembly based on revised length.
- * d) Once full re-assembly of (actual length) TCP data is done, pass off full frame to selfm
- * dissector to have 0xFF pairs stripped and the protocol dissected as per normal.
- * I'm not sure if tcp_dissect_pdus already supports this functionality, but I didn't see any examples?
- *
- * 3) Generally, the auto-configuration process itself will exchange several "configuration" messages
- * that describe various data regions (METER, DEMAND, PEAK, etc) that will later have corresponding
- * "data" messages. This dissector code will currently save and accurately retrieve one set of these
- * exchanges (0xA5C1, 0xA5D1, "METER" region) using the GArray and conversation functions built into
- * Wireshark. That said, a future modification would be nice to capture and retrieve multiple sets
- * of configuration messages to be able to decode all the different "data" messages encountered in
- * future exchanges.
