Author: tuexen Date: Fri Feb 10 22:57:50 2012 New Revision: 231462 URL: http://svn.freebsd.org/changeset/base/231462 Log: MFC r225559: Ensure that 1-to-1 style SCTP sockets can only be connected once. Allow implicit setup also for 1-to-1 style sockets as described in the latest version of the socket API ID.
