Re: overriding built-in dissector

[Robert Cragie <robert.cragie () gridmerge com>]

If I were you, I would just modify packet-dis.c and rebuild Wireshark. I
wouldn't call the process laborious and time consuming, although that may
depend on what environment you use (I build on Windows and Linux). There is
a certain amount of tools setup to do but follow the steps here and you are
unlikely to go wrong:
