> Per draft-ietf-tsvwg-sctp-failover-03 Section 5.1.6:
>
> Additional (PMR - PFMR) consecutive timeouts on a PF destination
> confirm the path failure, upon which the destination transitions to the
> Inactive state. As described in [RFC4960], the sender (i) SHOULD notify
> ULP about this state transition, and (ii) transmit heartbeats to the
> Inactive destination at a lower frequency as described in Section 8.3 of
> [RFC4960].
>
> This also prevents sending SCTP_ADDR_UNREACHABLE to the user as the state
> bounces between SCTP_INACTIVE and SCTP_PF for each subsequent strike.
