I was notified by Randy Stewart that lksctp claims to be "the reference implementation". First of all, "the refrence implementation" was the original implementation of SCTP in usersapce written ty Randy and a few others. Second, after looking at the definiton of 'reference implementation', we don't really meet the requirements. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
