Wireshark · Ethereal-dev: Re: 2nd Try: [Fwd: [Ethereal-dev]: Question about adding convers ations]

[Manu Pathak <mapathak@xxxxxxxxx>]

Hi Francisco,

   Yes, sorry I forgot to attach packet-rsvp.h. It's attached with
this message. I actually did manage to figure out what the problem
was; the call to tap_queue_packet() was in the wrong place. It
should have been at the end of dissect_rsvp() instead of
dissect_rsvp_msg_tree(). With that change, I was able to get the
basic stuff working. I still need to enhance the conversation stuff,
but the essential problem is taken care of. I will send a patch with
the final stuff when I am done. Thanks for your help! Regards,

Manu
