I can't see were we lost this functionality, but it is
straight-forward to add it [back]. Note that the change introduces a
"Decode As ... " "BER", which I what I would have expected (rather
than "ASN.1").
However, much of the "Data" in your example capture file does not
appear to be valid ASN.1 (Frame 6 seems to have the first valid ASN.1)
For example, the Data in the first packet frame starts "00A3..." "00"
is EOC and "A3" is a length which does match the length of the
remaining data. However, this is a use of EOC I am not familiar with
(and neither is Wireshark at the moment). EOC is usually used with a
"00" length at the end of indefinitely encoded constructed BER.
So before I commit this change, could you confirm that you do really
want to decode ASN.1 over transport (with no intervening layer),
and/or maybe point me at this use of EOC?
Of course, this may be the bug you are trying to diagnose with Wireshark.
