Hello Jenkins Builder, pespin,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/33715
to look at the new patch set (#2).
Change subject: MME_Tests: add Gn interface
......................................................................
MME_Tests: add Gn interface
To test the planned Gn connectivity support in open5gs MME the testsuite
also requires support for such an interface. This patch adds the
connection handler, provided by GTP_Emulation.ttcn to the connection
handler in MME_Tests.ttcn, along with a simple GTP ECHO REQUEST
testcase.

Change subject: GTP_Emulation: make GTPU optional
......................................................................
GTP_Emulation: make GTPU optional
When using the GTP_Emulation connection handler one has to configure a
GTPC and a GTPU link. However in some situations (e.g. when testing the
Gn interface of an 5g MME) only GTPC may be required. So lets make the
GTPU link optional.

I had problems receiving the GTPC ECHO RESPONSE. It got stuck in the GTP_Emulation.
See: https://gitea.osmocom.org/ttcn3/osmo-ttcn3-hacks/src/branch/master/library/…
There is a CLIENT_DEFAULT port through which we could in theory receive the response but I do not know how I should use it. I tried to use it by connecting it to vc_conn:GTP like so: connect(vc_conn:GTP, vc_GTP:CLIENT_DEFAULT); but this did not work.
The next option was to register a TEID into the TidTable, so I just registered '00000000'O and now I get the response. This is probably not good a solution. Maybe we should get the CLIENT_DEFAULT port working.

Because it's defined in `libosmo-netif`, and I don't really want to add a new lib dependency just to know size of a header...

And yes, the returned `len` does include +2 for ` struct amr_hdr` if it's not negative.

`osmo_amr_rtp_dec()` ensures that msgb has enough data in it, not only `struct amr_hdr` but also as much payload bytes as needed for the indicated `AMR FT`. So this is not really needed, we return early above if msgb is incomplete.
