dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/34266 ) Change subject: MME_Tests: Add S11/GTPv2 interface ...................................................................... MME_Tests: Add S11/GTPv2 interface The S11 interface is used by the MME to talk to the SGW-C. At the moment we do not simulate the S11 interface in our testcases. This is in particular a problem for TC_s1ap_attach, which needs to answer the Create Session Request, comming from the MME in order to continue. As a first step, lets add evrything that is required to run an S11 interface in the testsuite.
