Author: jhb Date: Fri Mar 1 03:05:08 2013 New Revision: 247526 URL: http://svnweb.freebsd.org/changeset/base/247526 Log: MFC 245823,245824,246210 - Use decimal values for UDP, TCP, and UNIX domain socket options rather than hex to avoid implying that these constants should be treated as bit masks. - Add placeholder constants to reserve a portion of the socket option name space for use by downstream vendors to add custom options.
