Dissector development- Problem with Conversation

[Sumit Kalsait <SKalsait () phoenixcontact com>]

Hello Everybody

In last days I was developing wireshark dissector for our protocol. for 
that reason In my dissector i used the conversation methods. as described 
in README.developer. Normally it register conversation like below.

A= Master, B= Slave 

A -------> B ( Master to slave)
B <------- A ( Slave to Master)


as 1 converation. as per wireshark standard. and I can associate next or 
consecutive packet (with A and B address) with this conversatin.

In my case We have listener module for our protocol so it see above 
conversation and gives packets to my Engineering PC so that I capture in 
wireshark 
C= Listner
D ------> C   (same like. Master to slave)
E <------ C   (same like. Slave to Master)

same conversation as described above(1 st conversation). Listner picks up 
same packets only changes address.
(for example D----> c is nothing but A---->B [Master to slave] and E 
<----- C is B <------- A  [Slave to Master])

And right now I want my dissector shold response in same way as above. So 
i can associate next or consecutive packets to this conversation
(I dont want to have D-------> C and E <-------C as 2 different 
conversation)

But How I can register listner module conversation ???  When I use my 
normal A-B and B to A it register as 1 conversation. but in case of 
listner i see my conversation registration is quite different. how could 
be this problem handled.

Thanks in advance


Many Thanks and Best Regards
Sumit
