Forwarding the discussion at Wireshark gerrit at https://code.wireshark.org/
Devices dumping NAS messages can give both encrypted and plain messages. At
least for Qualcomm LTE basebands it is true. Therefore using sub_type for
differentiating encrypted and plain NAS messages were discussed there. This
will likely introduce another modifications to gsmtap.h, and therefore want to
discuss more about this topic also here.
