Hello Bill, Guy,

Thus wrote Martin Kaiser (lists () kaiser cx):

Thus wrote Guy Harris (guy () alum mit edu):

2. The dissector processes both the pseudo-header and the actual
data.
  I.E., From the Wireshark perspective, the pseudo-header is just
  part
  of the captured data (similar to the code in your original patch).

  This is the approach used by packet-radiotap.c

At this point, I prefer the second approach.  The Linux USB dissector
now uses that, as of revision 32534; switching to that cleaned things
up.

thanks for the feedback. I'll define the pseudo-header for DVB-CI, apply
for a DLT and modify my dissector accordingly.

I uploaded a new version of the dvb-ci dissector to the bugtracker a
week ago, fixing the issues you found when reviewing the code. Before
that, I requested a DLT at the tcpdump workers list.  Unfortunately,
there's been no response yet. Any chance you can have a look and help me
progress this? (Guy, are you assigning the DLT values?)

Thanks,

   Martin
