Description

As we know, many production deployments have SGSN architecutres with clear control / user plane split.

In such situations, IP-SNS of the SGSN informs us of two (classes of) IP endpoints:
  • some that have control_weight > 0 and data_weight 0
  • some that have control_weight 0 and data_weight > 0

We need to be able to emulate this from our "SGSN Role" NS_Emulation, and enable this from the GBProxy_Tests in order to re-create such a scenario for osmo-gbproxy.

gbproxy,pcu,sgsn: Update config files

In upstream I9798e639b4bc8658482945970775b012b5840779 we introduce
two additional fields per NSVC (data_weight, signalling_weight). Make
sure those are specified everywhere.
