Wireshark · Wireshark-dev: [Wireshark-dev] [PATCH] Read VPI/VCI/CID information from K12xx .rf5 with extra_len == 0

[Kriang Lerdsuwanakij <lerdsuwa@xxxxxxxxxxxxxxxxxxxxx>]

Hello

I discovered that Wireshark K12xx detects the type of input (E1 timeslot 
or ATM)
based on the extra information. My previous patch to enable Wireshark to 
open
K12xx files with no extra information (extra_len equals 0 in SRCDEST 
record)
failed to give later dissectors the input type.

Attached is the patch to correct this for ATM PVC. It adds VPI/VCI/CID 
information
for display in the dissected tree (in k12_open function). k12_read and 
k12_seek_read
are also made more robust. These are reverse engineered based on hexeditor
and constants found in tektronix configuration file. Please apply the patch.

Best regards

Kriang Lerdsuwanakij
