QUIC/inet/tests/module/tcp_syn_6.test

%description:
Test connection setup: A performs active open, and B's SYN+ACK always gets lost.

Test that:
- initial RTO is 3s
- it doubles with each retransmission
- after some time, CONN-ESTAB timer goes off, and game over

Note: results are a bit weird, because both sides try very hard...
