Re: the Fragment offset field in IP packet should follow the Raw bitstream？

[Jaap Keuter <jaap.keuter () xs4all nl>]

That was a nice bit of source code archeology, but I’ve found that this format was changed in commit 7f6d5c04a86 with 
the comment:

    Don't show fragment offset as a bit field, but note number of bits used in long text.
    
    svn path=/trunk/; revision=22727

Note the date, that was back in 2007, so this format disappeared before Wireshark 1.0.
Where did you get this from?

Thanks,
Jaap
