stp: Support expect RFC466 4.5.1 DUNA after ASP ACT

libosmo-sigtran recently introduced support in SG role to send DUNA for unreachablew destinations when a peer ASP becomes activated. This is currently sent upon first ASP going active, since it's the time where SG assumes the ASP peer may need that information.

Depends: libosmo-sigtran.git Id9d92c3fda7423a9c79fffac6b650abba9651853 Change-Id: I6bee0f890a8baaa62be193824b1ae2fceb53fb45 --- M stp/STP_Tests_M3UA.ttcn 1 file changed, 31 insertions(+), 5 deletions(-)
