rS360751: MFC r355265: Restart RTT measurement
rS355265: When changing the MTU of an SCTP path, not only cancel all ongoing
Summary

After changing the MTU, all outstanding RTT probes are removed from the asoc.sent_queue.
However, no new RTO update is scheduled (net.rto_needed = 1).
This prevents the RTT / RTO from being updated on a regular basis and the net keeps using outdated values.
