Jacob Erlbeck jerlbeck at sysmocom.deThis patch extends the BSSGP patch code to also patch LLC information
elements along with MCC/MNC patching support for the following messages:
- Attach Request
- Attach Accept
- Routing Area Update Request
- Routing Area Update Accept
- P-TMSI reallocation command
Note that encrypted packets will not be patched.
