When comparing the output of the gsm_sim dissector (stk-fetch-example.pcap,
Decode User DLT 3 as gsm_sim) with the output of the gsm_a_dtap dissector
(stk-sms-example.pcap, Decode User DLT 0 as gsm_a_dtap) for the SMS
corresponding to the STK SEND SHORT MESSAGE proactive command I noticed two
(minor) problems:
1. The TP-MTI SMS-SUBMIT is incorrectly displayed as SMS-SUBMIT-REPORT.
The gsm_sms dissector uses (pinfo->p2p_dir == P2P_DIR_RECV) for mapping
to the correct msg_type and this should perhaps be set when calling the
gsm_sms dissector based on the given device identity (SIM to network).
2. The "SMS packing by the terminal required" command qualifier does not
seem to be taken into account before passing the SMS to the gsm_sms
dissector.

Reinhard
