The presence of one or the other may lead to some failure/crash in
some situations.

New tests: 0186xx for TDD with the huawei 3276 dongle.
All necessary files to configure and use it have been added.
Existing code has been adapted for the TDD tests.
Only the test setup v2 has been adapted.
The file test_case_list.xml has been changed to add tests
0186xx, but only to work with test setup v2. It won't
work with test setup v1. To be completed if needed.

The tests are similar to FDD tests.
Throughputs for TDD have to be adjusted, the throughputs
of FDD are used for the moment.

The throughput for the bandrich dongle was limited to 13Mb/s in downlink
UDP with iperf, with lots of packets lost (we sent 15Mb/s). TCP was
working fine.

Replacing /dev/ttyUSB2 by /dev/ttyUSB0 for wvdial solves the issue.

We also had to have separate data/control links. (See bandrich.txt
in cmake_targets/autotests/v2/actions for full details.)

The old one is still usable by replacing .gitlab-ci.yml with
the previous version.
