%description:
Test connection setup: A performs active open, and its ACK of SYN always gets
lost.

Test that:
- initial RTO is 3s
- it doubles with each retransmission
- B it retries SYN+ACK a number of times, then CONN-ESTAB timer goes off
- for A, connection setup seems successful at first, but will fail when it
  starts to send data
