[M] Change in osmo-ttcn3-hacks[master]: stp: Fix brokeness in STP_Tests_M3UA.TC_tmt_loadshare

by pespin

pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/39651?usp=email ) Change subject: stp: Fix brokeness in STP_Tests_M3UA.TC_tmt_loadshare ...................................................................... stp: Fix brokeness in STP_Tests_M3UA.TC_tmt_loadshare The test was not even setting the traffic-mode in the IUT. Furthermore, it was expecting pure round-robin behavior, which was the older behavior of osmo-stp when loadshare traffic-mode was selected. Actually split the test into 2, naming them properly (since round robin is not a AS traffic mode in itself, but a possible implementation of the loadshare traffic-mode. The new test validates the usual loadshare traffic-mode based on SLS distribution.

[M] Change in osmo-ttcn3-hacks[master]: stp: Fix brokeness in STP_Tests_IPA.TC_tmt_loadshare

by pespin

pespin has submitted this change.

Since in IPA so far the SLS is fixed per ASP, we need to add an extra sender ASP which will get a new asp_id (and hence SLS) so that we can also test traffic being sent/distributed to the 2nd receiver.
