Hi,
I've been advised by Graeme Lunt to post to this list regarding a small
issue with STANAG 5506 handling.

I'm using wireshark 1.0.6 SVN Rec 27387.

According to S'5066
For S_UNIDATA_IMPLICATIONS:

The following four arguments shall (9) be present in the
S_UNIDATA_INDICATION
S_Primitive if and only if the Transmission Mode for the U_PDU is equal
to Non-ARQ
w/ Errors:
a) The Number of Blocks in Error
b) The Array of Block-Error Pointers
c) The Number of Non-Received Blocks
d) The Array of Non-Received-Block Pointers

The final argument, U_PDU, shall (16) contain the actual received user
data for delivery to
the client.


However when the transmission mode is "Non-ARQ / Broadcast"
Wireshark interprets the U_PDU as the error block.
It then looks like wireshark incorrectly think that the
S_UNIDATA_IMPLICATIONS is malformed.


Cheers,
Peter
