What do we tell all our users when our kernel SCTP code
no longer works?

It uses SO_REUSADDR, SCTP_EVENTS, SCTP_NODELAY,
SCTP_STATUS, SCTP_INITMSG, IPV6_ONLY, SCTP_SOCKOPT_BINDX_ADD
and SO_LINGER.
We should probably use the CONNECTX function as well.

I doubt we are the one company with out-of-tree drivers
that use the kernel_socket interface.
