osmith has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/38546?usp=email ) Change subject: bsc: testenv: set MTU=1500 for lo ...................................................................... bsc: testenv: set MTU=1500 for lo Two tests are failing if the MTU is 65536 instead of 1500. This is an upstream bug in titan.TestPorts.SCTPasp: https://gitlab.eclipse.org/eclipse/titan/titan.TestPorts.SCTPasp/-/issues/3 Add a workaround so the behavior of the test environment is the same as with docker-playground and the tests can pass again.
