Hi,

You could take a look at the CDP dissector:
http://anonsvn.wireshark.org/wireshark/trunk/epan/dissectors/packet-cdp.c

It has basically the same problem, which it solves by re-using the ett 
value.

Thanks,

Hi
I am writing a plugin for dissection of MIH protocol.
https://bugs.wireshark.org/bugzilla/attachment.cgi?id=6547
This protocol contains all the information in form of TLVs(type 
length
value), also this protocol does not specify the maximum number of 
TLVs
inside a packet. I am confused in the display of the TLVs. I tried it
with
assigning a subtree to each TLV, is there any better way of doing it?
-> Also, in the plugin I have set the number of TLV subtrees to 20, 
but
that is not a good way of doing it, can someone also tell me how to 
set
variable length subtrees in ett array.

Regards
Ankith
