Function sctp_CheckTimers

freebsd/netinet/libalias/alias_sctp.c:2471–2497

@ingroup Timer * @brief Check timer Q against current time * * Loop through each entry in the timer queue since the last time we processed * the timer queue until now (the current time). For each association in the * event list, we remove it from that position in the timer queue and check if * it has really expired. If so we: * - Log the timer expiry * - Remove the association from the NAT

 * @param la  Pointer to the relevant libalias instance
