net: sctp: bug-fixing: retran_path not set properly after transports recovering (v3) When a transport recovers due to the new coming sack, SCTP should iterate all of its transport_list to locate the __two__ most recently used transport and set to active_path and retran_path respectively. The exising code does not find the two properly - In case of the following list: [most-recent] -> [2nd-most-recent] -> ... Both active_path and retran_path would be set to the 1st element. The bug happens when: 1) multi-homing 2) failure/partial_failure transport recovers Both active_path and retran_path would be set to the same most-recent one, in other words, retran_path would not take its role - an end user might not even notice this issue.
