Hi  Sake,

I was fumbling around tshark and was getting close, but you did a far better
job than I did.  I was looking for the IP.id to correlate when I compare two
trace files.

I would prefer a way to do it in the GUI, but will do nicely.

Given those specific requirements (ip header field, GUI) , why doesn't

Edit->Preferences->Columns->New->
Title: <arbitrary-text-string>
Format: Custom
Unlabeled text box to the right of the Format drop-down control: ip.id (display filter syntax appears to work, at least in this case)
->OK

meet your needs? Wireshark appears to both display & export the new column.

Thanks

If I understand you correctly you want the Info column to display the values as if IP was the last layer that was dissected by Wireshark?
I thought that would be possible to achieve by disabling all protocols 
and then enabling only Ethenet and IP. But unfortunately the IP 
dissector then just displays: "TCP (0x06)".
    
Hmmm... I looked at epan/dissectors/packet-ip.c and it shows that only
exceptions are put into the "Info Column". This makes sense as IP will never
be the last protocol, there will always be a protocol on top of it. If it
doesn't that protocol, it will just show "<name> (<proto-id>)".

When I disable the HTTP dissector, the Info Column will indeed show the TCP info like there was no upper layer present.
Do you want the IP dissector to behave in the same manner? 
(ie showing IP details in the Info Column when the upper layer 
protocol dissectors are disabled)
    
What info do you want exactly? I think you can use tshark to accomplish your
goal. Let's have a try..

$ tshark -r trees.cap -T fields -e frame.number -e frame.time_relative -e
ip.src -e ip.dst -e ip.len -e ip.id -e ip.ttl -e ip.proto  -e ip.checksum -E
header=y frame.number frame.time_relative ip.src ip.dst ip.len ip.id
ip.ttl  ip.proto        ip.checksum

Does something like that fit your needs?
