Greetings,
I have been working with wireshark and SIMtrace.
And decided to extended the dissector for 'GET RESPONSE' (mf/df/ef) and
'STATUS' - according to the ETSI 11.11 Section 9.2.1 Page 39 - 41 and Page
46 (Definitions and Codings for response params)
Keeping update with latest wireshark commits.
I would like to commit to their gerrit.
Please could you let me know here - if the output is as expected.
Let me know your views/comments on the output so I can change it before
commit.
Also code can be viewed here 'https://github.com/GerardPinto/wireshark'
(properly forked and synced with upstream) or
reviewed by wireshark gerrit (Once I get your views on the output).

(3) STATUS ( ETSI 11.11 Section 9.2.2) says -

of the SELECT command in case of an MF or DF.
