Turns out IP_LOCAL_PORT_RANGE works for SCTP out of the box after all. What I didn't notice earlier is that sctp_setsockopt() delegates to ip_setsockopt() when level != SOL_SCTP. CC'ing Marcelo & Xin, to confirm that this isn't a problem.

Yes, SCTP supports ip_local_port_range by calling inet_sk_get_local_port_range() in sctp_get_port(), similar to TCP/UDP.

Well, that's embarassing. I see that I've updated sctp stack to use inet_sk_get_local_port_range() in 91d0b78c5177 ("inet: Add IP_LOCAL_PORT_RANGE socket option"). Thanks for confirming, Xin. It's clearly an overside on my side. That SKIP in tests should have never been there. I will send a fixup.
