====================
Netfilter fixes for net
1) Perform SCTP vtag verification for ABORT/SHUTDOWN_COMPLETE according
to RFC 9260, Sect 8.5.1.
2) Fix infinite loop if SCTP chunk size is zero in for_each_sctp_chunk().
And remove useless check in this macro too.
3) Revert DATA_SENT state in the SCTP tracker, this was applied in the
previous merge window. Next patch in this series provides a more
simple approach to multihoming support.
4) Unify HEARTBEAT_ACKED and ESTABLISHED states for SCTP multihoming
support, use default ESTABLISHED of 210 seconds based on
heartbeat timeout * maximum number of retransmission + round-trip timeout.
Otherwise, SCTP conntrack entry that represents secondary paths
remain stale in the table for up to 5 days.
This is a slightly large batch with fixes for the SCTP connection
tracking helper, all patches from Sriram Yagnaraman.
