This is a replacement of the existing decoding of ERF files (Extensible Record Format from Endace). For the decoding of the ERF files, according to the "type of record" given in the ERF header, several decoders can be used. Up to now, the decoder is determined according to an environment variable, or with a kind of heuristic. And, all the treatment is done during the file extraction. The new architecture, will separate the ERF file decoding, and the ERF record decoding. The ERF records will be decoded with a specific dissector. This dissector can be configured with options, to replace the environment variable. http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1839 svn path=/trunk/; revision=23092
