The newer wireshark versions are displaying the DIAMTER Command Code not
correctly. The R bit is not considered and so an AA-Request (AAR) is displayed
as AA-Answer (AAA) because both have the same code (265)
In older versions the decoding was correct, but I can't remember since when
it's not working any more.
Please consider the R bit during decoding and display this in the Packet List
window (Info) and in the Packet Details window (Command code text).
Thanks
