The ovskey flow-string parser has no OVS_KEY_ATTR_SCTP entry, so a flow string containing sctp(src=.../dst=...) parses without error but silently drops the L4 key. The resulting flow carries only ipv4(proto=132), and the kernel rejects it: match_validate() in flow_netlink.c requires OVS_KEY_ATTR_SCTP when the IP protocol is IPPROTO_SCTP and returns -EINVAL for the missing key. Register OVS_KEY_ATTR_SCTP in the parse table and add a matching selftest that verifies SCTP flow key matching (sctp src/dst port). One listener serves the whole test. socat's fork option handles each association in a child, so the flow rules are the only thing that changes between the three phases and the listener is never restarted underneath them. -t 1 bounds how long a forked child lingers after its association closes, and the existing kill -TERM of the captured pid on teardown removes the listener itself. Also enable CONFIG_IP_SCTP in the selftest kernel config. The config checker strips underscores before comparing keys, so the entry sorts before CONFIG_IPV6 rather than after it.
