SCTP_ASCONF_SUPPORTED sockopt is used to set enpoint's asconf
flag. With this feature, each endpoint will have its own flag
for its future asoc's asconf_capable, instead of netns asconf
flag.

Is this backed by a RFC? If yes, it should be noted in the patch
description.
Quickly searching, I found only FreeBSD references.

RFC doesn't define this sockopt clearly, unlike prsctp and reconfig,
not sure why.
but BSD supports it, so does some userland SCTP.
