Hello.
sgsnemu cannot establish PDP context with latest Cisco GGSN.
There is additional information element "Bearer control mode" sent by GGSN
in create PDP context response message (attachment).
This information element is not recognized by sgsnemu.
Here are the changes in libgtp to support this information element:
